I know this is an old subject but as a newer member perhaps someone might have an idea. Yesterday I folded the wings on my 2001 Kitfox  4-1200 to install some new fuel tank sight gauge tubes. While folded, I removed the fuel caps and took a look inside my tanks to see if the sealant Kreme had been used in my tanks as this was a recently purchased aircraft. Sure enough there was that creamy color. One tank looked OK (at least from what I could see) but the other had a small area along the bottom of the outer edge where it appeared the stuff was shrinking and cracking.It resembled a prune and  had slightly pulled away from the Fiberglas. I don't think any of it has come off(yet) but I was wondering how long I might have before this happens. I will keep a constant watch. My gascolator screens were clean.

   Is my only solution to remove the tanks and replace them with the plastic tanks offered by another company? I sure hate cutting these tanks out as I am not an experienced fabric guy although I have watched a bunch of it being done and will of course get the books and do it if I have too. I can't see that removing the wings and filling the tanks with a solution of MEK and shaking it around would do much good to get the old stuff out as some guys have done.

   Any input would be greatly appreciated as you guys were the ones who alerted me to the problem in the first place. I am sure there are other Kitfoxes with the same undiscovered problem.

                                   Thanks,

Your plight is a familiar one, Dick, and by the sound of it, you definitely  have the Kreem coming loose.  This was caused in many tanks by failure  of the Kreem applier to properly clean away the mold  release before applying the Kreem. There are a lot of them out there  like this.  It's possible for the Kreem to release in sheets and  potentially block flow from the tank.  This happened to a guy on one of the  Alaska trips, but a field repair was able to be made. 

 1.  The easiest way is to remove the wings, get a few people to help,  use MEK or Acetone to remove the old Kreem, then either leave them unsloshed or  reKreem using a 50/50 Kreem/MEK mixture. 

 2.  If you don't like that option, you can remove the tanks from the  wings, and do the same thing as above, then reinstall the tanks, make a fabric  repair, repaint, be on your way and never look back.

 3.  The most expensive is to replace the tanks.

 It's all based on choices, but none of them are very difficult.

 If it were me, I'd do #2.

Hi Dick-

I disagree with your assessment of taking the wings off and sloshing,  

as a means of cleaning out the old Kreem. It works, and works well,  

apparently. I've got about 475 hrs on mine and going on 2-1/2 yrs  

since I did my tanks...already in the wings. I had called the former  

Skystar Co. for advice and they told me that since the tanks were, at  

that time, about 11 years old and had had nothing in them (don't know  

whether this makes any difference), that I should slosh with acetone  

and re-Kreem. I had a set of wing rotators which made it pretty easy  

to get the tops and bottoms of the tanks, but getting the ends was  

another matter, but not impossible. The acetone completely dissolved  

the old Kreem, and I kept draining and re-sloshing with newer acetone  

until it ran clear. Same method for re-coating with Kreem, diluted  

with MEK 50/50.



Now, I've got to preface my no problem status...I have used nothing  

but 100LL except for about 9 gallons of premium. I can't speak to  

using anything but 100LL, as  I don't know how the Kreem will perform  

if using autofuel w/E-whatever.

Deke,Lee and Lynn ,Thanks for your input. I am now reconcidering removing the wings and cleaning the tanks with the tanks in place. I read the Alaska account and prior threads on that method.It just seemed that the removal and application of the Kreem would not work well but maybe so. I am using nothing but auto fuel in my 912UL and so far it does not have alcohol but it will be coming I know.Our governor is "hot on the trail" for it's use here in Florida.Is there nothing better than Kreem ? Is it affected by alcohol in the fuel?

  Lynn,I read in the info about the plastic tanks that the installation proceedure requires cutting out the tops of the fiberglass tanks and installing each 5 gal tank in the cavity then covering the top of the tanks with 1/8 " plywood and then recovering.I wonder if that would be structuraly strong enough if the fiberglas tanks were required as part of the wing structure ?  I do know that a set of 4 tanks(20 gal) would be expensive (about $1100)

"Likely" stronger once you use spray foam to bond the new tanks to the existing ones. I think the 1/8" plywood is just a top cover but might add a bit of strength. 



Now that being said after going through thousands of gallon on gas in my wingtanks and ethanol auto gas , I have had NO ISSUES YET.  If I do I will likely resort to these  http://www.wingtanks.com/ and add an extra  tank on each wing.   for 1100$ that seems like decent fix to a problem that IF you had would make your plane --> FLYABLE   or NOT FLYABLE.



Also I have No creme in my tanks nor would i ever put  it it to a perfectly good tank.

Has anyone used the Bill Hirsch tank sealer? From the literature, he is advertising it is the only one used in aircraft tanks. It too is MEK soluable,alcohol proof,etc. Other articles on the net talking about tank sealers sure" bad mouth" Kreem while saying this stuff is great.  It sounds like it might be the same stuff?

I'd be the last one to comment intelligently about the wing/tank  

structural element, but it sounds like maybe if you left enough of  

the lip around the fiberglas tank that it might work, provided that  

you got a good bond with the plywood. Wait a minute though....there  

are baffles inside the f'glas tank that attach to the tank top, and  

I'm sure that these would have to go if you were to cut the tank top  

off. I'm pretty sure that these baffles add a bunch of structural  

strength to the tank, and resist the flexing or twisting of the wing.  

I'm no engineer, but I think if the original tank plays the important  

role in wing construction that I've read here, maybe just adding the  

plywood...even the best aircraft grade...wouldn't be enough. But if  

you could tie the plywood into the baffles somehow, then maybe....



If it was me, I'd round up some help, clean and re-slosh with Kreem,  

and head for the nearest 100LL pump. That way instead of paying $1100  

for the tanks, you can apply that money to your fuel bill. : ) And  

speaking of rounding up help, they don't have to be there the whole  

time the tanks are soaking. Just get the tanks off, plug all the  

holes, put in about 5 gallons of acetone when wings are level and let  

it sit for several hours, flop it over...trying to think how I  

plugged the filler neck....rubber and a hose clamp?...and let it soak  

some more. The more acetone you use the less time you have to spend  

trying to get the ends of the tanks done. Do a couple of applications  

of clean acetone, until it comes out clear. Mine did not come out in  

sheets, but dissolved, turning the acetone to a whitish color. After  

allowing to dry out, mix the new Kreem 50/50 with MEK and go through  

the same ritual as the cleaning...that is, rotate and let sit, rotate  

and let sit. Drain out excess and you're done.



I don't know about how alcohol affects these tanks, so I'm hoping I  

never have to learn the hard way. But if you go to Kreemed tanks and  

100LL, you'll bypass this problem and only have to worry if they do  

away with 100LL. But there'll be a bigger lobby against losing 100LL  

than there is (I think) for keeping alcohol out of our mogas.

Well My wings got folded last night and I just check the tanks. 

By lifting on the front spar with the wings folder and putting a finger where the tank meets both front and rear spars, there is movement.

are my wings compromised for strength? or is that the way they are. ? 

Older ones never had wing tanks. 



So are the tanks structural? I am not sure but by mounting one of the plastic tanks and foaming it in place I think it would gain strength. How much ? now idea. Who has in fact installed these wingtanks.com tanks ? 

I actually like them as they look to be made of the same material that my dash tank is made of .

We have done some changes over that past 6 months... although I do not think our tanks as of 1996 to 2007 have had any specific issues. (no reported issues)

 

 As of this year we are using a new resin.  To date.. we have put some pretty harsh materials in them with no effect.  For the last several months they have had both 10% and 85% ethanol fuels in them and no effect.

 

 I will not go into the details of the resins as it is proprietary information.

 Good points Lynn.  All this talk has reminded  me of old--some of them very old--discussions regarding the wing tanks being  structural.  The question in my mind was then, and still is,   "Are the wing tanks required for structural integrity or do the wing  tanks become a part of the structure when they're installed?"  In  my mind it would be the latter.  The wing tanks were not initially part of  Kitfox wings.  They evolved from the (1) panel tank to a (2) panel tank and  six gallon aluminum tank on one side to a (3) to a six gallon aluminum tank on  each side to the (4) 12 gallon glass tanks that we now have.  As I recall there are some out there with a 6 on one side and  a 12 on the other.  

  

 Installing the new poly tanks inside the existing  tanks shouldn't be any problem nor, IMO, would it require any additional bracing  other than the recommended sheet of plywood on top for protection.   Personally, I agree with what Lynn said.  Clean them up, reslosh if you  must, then run 100LL if worried about the Ethanol.  You can run a lot of  that stuff through there for the money it would cost to replace the tanks.   Another thing is that the ethanol can be diluted by going 50/50 with Ethanol  auto gas and 100LL.

  

 Another note.  The sloshing was applied  not to protect the tanks against chemicals, but to fill in and seal the  tiny pin holes in the tanks from the fiberglass weave that caused fuel to  wick/seep through the fibers creating a smelly tank.  This was all  done before Ethanol was a factor.

  

 As for whether Kreem is a good product or not, be  sure to get your facts before you pass on anecdotal evidence gleaned over the  The mighty internet.  I always approach anything I read on the net with a  healthy dose of skepticism.  Kreem has been around a long time and it is  used in many types of tanks, not just aircraft.  When all of this started,  other than Randolph, Kreem was about all we had.  Now there are other  options of course, which is a good thing.  

  

 So, before you make a decision on what course of  action you take, if any, I suggest you do some research.  This Ethanol  stuff is still evolving and products will keep emerging as the evolution takes  place.

 FWI W...

GREAT QUESTION  !!  Like i said I have put thousands of gallon of gas through my tanks that are from 1992  .Gas has varied from Premium,marine gas pump fuel,av-gas and Regular gar for the most part and what ever resin is in mines has held up so far .   About 3 or 4 year ago I had a quick drain valve fell out in my hand.  I kneaded together some epoxy stick and stuffed it in there and it never leaked since.  I use same epoxy putty on main fuel dash tank for pipe thread sealer and for the nuts to hold dash on. they pulled right out once leaving a hole right into the tank.

I've had 91 octain fuel in my wing tanks sense 1993  and sometimes 100 LL and never had a problerm

 yet. Haven't used Ethanol fuel that I  know of.

The original Kitfox Wing had a drag/anti braces where the tank is.  When looking at the instructions you would find that if one was to retrofit a early model IV wing with a wing tank that the drag braces need to be re-positioned..

Good points Lynn.  All this talk has reminded me of old--some of them very old--discussions regarding the wing tanks being structural.  The question in my mind was then, and still is,  "Are the wing tanks [i]required[/i] for structural integrity or do the wing tanks [i]become a part[/i] of the structure when they're installed?"  In my mind it would be the latter.  The wing tanks were not initially part of Kitfox wings.  They evolved from the (1) panel tank to a (2) panel tank and six gallon aluminum tank on one side to a (3) to a six gallon aluminum tank on each side to the (4) 12 gallon glass tanks that we now have.  As I recall there are some out there with a 6 on one side and a 12 on the other.    

   

Installing the new poly tanks inside the existing tanks shouldn't be any problem nor, IMO, would it require any additional bracing other than the recommended sheet of plywood on top for protection.  Personally, I agree with what Lynn said.  Clean them up, reslosh if you must, then run 100LL if worried about the Ethanol.  You can run a lot of that stuff through there for the money it would cost to replace the tanks.  Another thing is that the ethanol can be diluted by going 50/50 with Ethanol auto gas and 100LL.  

   

Another note.  The sloshing was applied [i]not[/i] to protect the tanks against chemicals, but to fill in and seal the tiny pin holes in the tanks from the fiberglass weave that caused fuel to [i]wick/seep [/i]through the fibers creating a smelly tank.  This was all done before Ethanol was a factor.  

   

As for whether Kreem is a good product or not, be sure to get your facts before you pass on anecdotal evidence gleaned over the The mighty internet.  I always approach anything I read on the net with a healthy dose of skepticism.  Kreem has been around a long time and it is used in many types of tanks, not just aircraft.  When all of this started, other than Randolph, Kreem was about all we had.  Now there are other options of course, which is a good thing.    

   

So, before you make a decision on what course of action you take, if any, I suggest you do some research.  This Ethanol stuff is still evolving and products will keep emerging as the evolution takes place.  

FWI W...
