Posted: Wed Jan 17, 2007 4:00 pm Post subject: Fuel Tanks

I've looked at the archives on fuel tank problems and fixes and I gather  

Skystars last fuel tanks where built using a vinyl ester resin.Has  

anyone using that tank experienced problems with auto fuel and the  

additives?I've pulled the 13 gal.tanks on my 1992 IV 1050 and I'm  

concidering buying Johns new tanks and I'd like to continue to use  auto

  

 I did not build my plane but I think my tanks are  exactly what you are talking about and they have always had auto fuel or mogas  as I call it in them and been no trouble at all. I can't tell you though if they  have been sloshed except the fact they are a straw colour to see the fuel level  through the end of the tank and so it is difficult. This makes me wonder if it's  sloshing causing this but I don't know. It just seems to me that if all tanks  are so hard to see the fuel level through then there needs to be another  solution.

                                                                                                                                                                                       Rex.

G'day John, I also had problems with my glass tanks  and posted pictures of the factory defects on Sports Flight. What I did to  resolve my problems was to remove each tank and recover them with epoxy and then  slosh each. Turned out great and no problems to date. I was fortunate in  that I was rebuilding the wings at the time so the tanks were easy to remove. I  did establish however that you can remove the tanks from the wing without having  to remove the inner wing rib as has been advise here from time to time. Each end  of the tank sits on a bed of silicon which with patience can be removed and the  tank slipped out. Its a tight fit and you may get a bit of pressure placed  on the under wing fabric but they will come out.

  

 Regards

Hi there, Has anybody ever designed or built add-on auxiliary  fuel tanks? I have only got a pair of 6 gal fuel tanks and planning a long  flight to Oshkosh this summer and it would be nice to have an extra few gallons  of fuel on board? Any Idea's out there?

                                                                                                       Jim

Hey Jim, 

  

 I brought up this topic recently and suggested I might do the same . 

 I was thinking of a 5 to 10 gal tank right behind the seat.  Also  making a larger baggage compartment as well. 

 Perhaps make a exterior access door as well. 

 For the record I have carried 6 Imp Gals behind the seat on occasion which  is about 45 lbs inclding containers. Plus another 30 pounds of bagger ther as  well so I think 10 gal tank against the back of seat would most likely work  out  w &  B  wise. 

  

 Definatly a possiblilty. 

  

  

 Dave

You could use a tank strapped to the bottom  of the fuselage similar to the cargo pod.  When you run low of fuel in the  wings just pump gas into the wings through a "T" in the gas line with a hand  pump.  A similar system to this was used by the flying gas cans we  used to see passing through here on their way to Europe via the Azores.   The nice thing is you could remove the tank quickly to save carrying excess  weight on local flights.  It will probably slow the plane down a bit but  gees the 'Fox is going to be slow anyway.

  

 My plane has a small stowage compartment  behind the seat, accessible from the outside, rated by the original builder for  50 Lb.  I have a hard time getting 10Lb survival/first aid kit in it.   I also have a small box mounted overhead on the right side of the cockpit for  very small items... Gas strainer..plugs and plug wrench etc...

  

 I can carry up to 30Gal U.S. in my float  compartments.  Only problem is I have to land to transfer it to  the main tanks.  

  

 I think the belly pod idea is best because  you can position it right at the CG and remove it, when not needed.  If you  are into spending a winter working on the wings I'm sure John McBean, Kitfox  LLC. will be happy to provide you with 13 Gal wing tanks.

  

 Another idea is to install two small  temporary tanks, similar to those used on some small UL, high on the wing  struts.   you will be able to get gravity flow from these tanks but  you will need to have shut off valves for them so fuel from the main  tanks won't cause them to overflow.  If mounted high on the strut there  will be less load on the struts and the fuselage.

  

 To state the obvious... Any of these things  could cause the plane to behave "differently".

They have football shaped auxiliary tanks that they attach to  some ultralights .

 You might be able to attach them to your struts .

Hi Dave,Noel, and Kem, I was thinking of finding a 12 gal plus fuel  tank that would fit nicely on the passenger seat? Not sure if that would be high  enough to gravity feed the header, if not it could be pumped in I  guess?   Jim

Jim,

 Could you replace the header tank with just a larger tank behind the seat  ?  

 Would be a shame to lose a pssenger seat to a fuel tank .

I put a aluminum 9 gal. aux. tank in my Avid. It was purchased at an 

off-road supply store for $99, and was light weight. It also had the fill 

cap and pipe fittings already welded in. It is built to take rough off 

roading and installed easily by attaching it to the tubing already a part of 

the fuselage.



It is cyndrical in shape and supprisingly small (for holding nine ga.).

Hi Ken, Where did you attach it? In cargo area?  Jim

Now, don't do as Michel Gordillo who flew his Kitfox from Madrid to 

Oshkosh, with a fuel tank instead of his right hand seat, until the 

Russians wanted him to take a navigator over Siberia! 



Cheers,

Michel

Are you using this tank Dave? If so, how'd you install it?

Marco,

  

 No but I am looking to put a tank right behind the  seat.

 I have 2  6 gal wing tanks now and a 8.5  gal  front tank  and another 10 gals would be nice when on floats and  remote.

Will you be able to do that without cutting fabric? I have 2x 6 gal wing tanks and 1 gal behind the seat header. Would sure like another 5-6 gal near the CG without cutting fabric.
