I admit to a less than perfect system.  My tanks are 20 year old chem  

jugs from my old employer.

Probably held coil cleaner or cooling tower additive.  Most likely  

should get new ones 

If I were to install a metal tank it would drain from the bottom  

too.  With a plastic one

I prefer not to weaken the floor with a hole.

I also have forgotten to shut power in emergency landings.  Seem to  

get too busy looking for

a good spot.  Last time the pump was squirting fuel straight out of  

the line.  May have cleaned

the prop a little.

The thought offered about the exhaust direction possibly creating a  

resonance will be considered.

 Bob B:

 I have always pulled fuel from the bottom of tanks, US, FS, and  

 mkIII.  I don't want the engine to quit and still have a gallon of  

 gas in the tanks to crash with.  

 Never did like multiple tanks and dip tubes, but that is strictly  

 personal.

 My engine driven pump does a good job of pulling fuel (flown at  

 14,500 feet MSL wide open throttle), although I help it along with  

 a Facet electric pump on takeoff, landing, and during low level  

 flight, which is most of the time. Would probably never get the  

 standby pump turned on if I lost an engine due to fuel pump on  

 takeoff, landing, or low level flying.

 I figure if I get myself into an impending crash I can turn off the  

 master switch and alternator switch which will shut down the  

 electrical system, and isolate it all the way back to the battery.   

 However, don't think I have ever remembered to do this on any of my  

 crashes to date.  Hardly ever hear of a post crash fire in a Kolb,  

 but there is always that one time.  I don't want to be the victim.

Bob B:



I haven't used a plastic jug tank since 1990.  Back then the wall thickness 

of the jugs seemed to be quite a bit thicker than the jugs that are being 

utilized today.



Popular in the UL world was a push in "elbow" pulling fuel out the bottom of 

the tank.  Used a large neoprene grommet.  These worked well for me.  Never 

experienced any problems with them.



I am still scratching my head trying to figure why folks use plastic fuel 

lines, when "good ole" black neoprene is readily available, cheap, durable, 

and reliable.  Only reason anyone has come up with is to see the bubbles in 

the line.  I think one of our fuel experts on the Kolb List some time back 

offered that gasoline "gases".  When placed in a vacuum, i.e., pulling fuel 

uphill, it pulls gas out of the fuel that looks just like air bubbles.  Back 

in the good ole days when I was running UL fuel line like everyone else, my 

fuel lines were always pulling bubbles.  Used to drive me crazy.  Pulling 

air through the fuel system, yet no fuel was leaking out when the engine was 

shut down or running.  Now...I don't see it and am not bothered with it.



I have, during preflight inspections of my US and FS, pulled on a fuel or 

pulse line and have it fail.  Never had that problem with black neoprene.

If you run a fuel pump below the level of the fuel and pressure feed it up to the engine, you will not have bubbles to worry about.   It is possible to have an engine failure from pulling fuel up to much of a distance, and it will most likely happen during full power = Takeoff.   The powerful fuel pump on the Rotax 912 does a pretty good job of pulling fuel uphill, but the gas can vapor lock under certain conditions which would lead to engine failure.



It is good practice to run an electric pump on takeoff and landing to pressure feed your engine driven pump.   We had someone post that is so paranoid about fire, he says not to run an electric pump on takeoff which is wrong, he is more likely to induce an engine failure and crash by doing this.   A fire after a crash can happen with or without an electric fuel pump running...  It is foolish to be so paranoid about the remote possibility of a fuel pump causing a fire, that you create a much greater hazard of an engine failure.   The best way to avoid a fire is to keep your engine running on takeoff and avoid a crash altogether.

describes.

Just some (mostly) clear "Tygon" that I ordered from Aircraft Spruce a

few years ago - I don't recall the exact description, besides that it

was advertised as fuel line.

Thanks, Russ!



After my preflight blunder of last summer (where I did not tighten my

oil cap and it went thru the prop, and I chose to execute a

precautionary landing on a "dry" lakebed - that wasn't exactly dry - and

I ended up having to haul my aircraft from the muck with a helicopter),

I guess I'm paying a little closer attention to the details of my

preflight check!

A lot of the degradation of the "blue fuel line" has to do with the sun.

If you'll notice - the bottom fuel line (maybe coming out

of your tank) inside the fuselage, will last a lot longer

than the fuel line going to your carbs that are exposed to direct sunlight

all the time.

The hazard with the fuel line from the auto parts store is that it's layered, usually with a webbing of some kind seperating the pleats. The idea here is it's designed for fuel systems that are under pressue, not under vacuum.



The problem is that the pleats can seperate over time; the inner pleat can then collapse under vacuum with the expected results.

I've used only the tygothane clear line from the usual a/c suppliers ever since.



I'd love to run Aeroquip line as well, but I havn't researched how to deal with the fittings on my tank and on the Rotax fuel pumps for a good attachment.



The tygothane lasts a long time and is a proven good solution on our light Rotax powered a/c. Works for me...

Oops forgot my second point.



The other HUGE advantage, the main advantage I'd say, of the clear line is the ability to inspect it. Being able to inspect critical systems is the life blood of flying those systems through the air. 



Opaque lines like the black neoprene lines cannot be inspected for problems without actually removing them and even then it's difficult to spot problems with the inner pleats in longer runs. So generally it just never is inspected except on the outside and it's quality has to be taken on faith. Not good......



The clear tygothane lines, on the other hand, can be easily and thoroughly inspected with it still on the plane and defects are easy to spot.



Don't ask me why I know this...



Having to change it out from time to time is, in my experience, a very small trade-off compared to the ability to inspect the lines conveniently and effectively. Well worth it...

Some black fuel lines start breaking down when an oil mix is run thru them 

after awhile and you can find small black pieces in the filer. The best 

black fuel line would be a marine grade used for gas and oil mixes.

Not necessarily.  Although most if not all newer cars have fuel injection 

and an electric pump located in or near the fuel tank pushing the fuel, 

there are lots of older cars out there using only an engine driven pump 

pulling the fuel from the tank.  I've owned some old cars with rubber fuel 

line looking so crispy that you'd think a feather touch would make it 

disintegrate, but it held even while the metal lines rusted out.



But I'll still use clear line on my various flying machines.

Hi everyone  I just wanted to post some \ info I know about fuel line.

many years ago there was the blue fuel line which was suppose to be the 

best.

and in many cases it was,   until someone introduced some blue crap that 

looked and felt the same as the

good stuff.   I suggest throwing it all away.  I made the mistake of 

putting some of the bad crap in my

dip type fuel tank on trike.   the hose broke off inside the tank  It 

didnt take long to go bad.

the yellow fuel line tubing  is tygon 4040 and  is NOT  TYGOTHANE  but 

can be used for fuel but NOT recommended.



there are 2 types of fuel line I only use.



Tygothane C210  ESTER is formulated for all type of fuel

Superthane  ESTER is supposed to be a near equivalent.

EITHER base will not hold up and will be a mistake.



this stuff can  be colored if you buy a million or more feet. Probably 

no one will buy

but generally the good stuff will be nearly clear

I personally use Superthane ester.  I have an account with new age

I purchase quantities from the company, New age and

there is a difference in the formulation



Both The makers of Tygothane

and the makers of Superthane

recommend:

 ESTER BASE Formulation for GASOLINE and fuels. 

Either base is not as good.

Lucien,     If you follow this link you can see how I did it. I used  Yamaha  Outboard fuel line  on the flex areas. I have used this type of line for  years due to it's durability. If you opt to used the squeeze bulb, it is the  best around.  Part #  6Y1-24306-55. I have an old one that is ten  years old and has always been used with oil mix.

I copied the following from New Age's website. Note the bit about

water and about modern fuel additives. I could find nothing about

ethanol tolerance.



Notes

^^Hydrolytic Stability -- For resistance to moisture and fungus,

SUPERTHANE ether is recommended (Ester polyurethane does not react

well with water, prolonged humid conditions, or attack from fungus.)

The ether-based formulation is listed by the National Sanitation

Foundation (NSF 61). It also resists attack from ultra-violet rays

making it a good material for outside use.



SUPERTHANE PU tubing is much more resistant to pressure and vacuum

applications than corresponding sizes of PVC or rubber.



^Although polyurethane is commonly used in fuel applications, due to

additives in today's gasoline and petroleum products, field testing

should be performed.

Now that's a super nice fuel system setup there....... 



Personally, like I said I like to be able to inspect fuel line, at least any that isn't something I know has a very low chance of deteriorating like aluminum lines connected by AN fittings... So my personal preference is clear line.



Now that said, I wouldn't worry about something like aeroquip line which even tho it's opaque, it's also not the rank stuff from the auto parts place either .



Last line change on my plane I was trying to figure out how to go aeroquip, but I couldn't figure out how to get AN fittings on the fuel pump, carburettor and tank outlets. At least not without major mods and without just clamping the hose on there which would have been a little lame.....



I had also tried to work up a metal line up to where it needed to flex at the engine, but couldn't come up with a good solution.....



Yours is really nice tho...

LS:



I got into UL'ing initially because it was the only way I could figure 

out how to fly again after retiring as an Army aviator.  I chose to 

live on my retirement beginning at the ripe old age of 40.  So far, 

nearly 29 years later, I have survived and have thoroughly enjoyed my 

last 24 years of experimental flying.



If I deleted all the items on my airplane that were obtained from 

Wal-Mart and "rank stuff from the auto parts place", I would be 

permanently grounded.



I find if a builder uses his head, he can obtain safe, reliable, 

efficient hardware to keep his bird flying, at much less expense than 

buying expensive aircraft stuff because it looks slick, and real 

airplanes are Federally mandated to be equipped that way.  Thank God 

for a little freedom of choice.  I am not knocking Steve B's 

beautifully finished FF that walked off with the S&F Grand Champion UL 

2008 trophy.  However, I was able to bring home the same trophy in 

1988 for my FS, plus two Gold Lindy Trophies from OSH, 1989 and 1993, 

using my old philosophy of using good quality stuff that will get me 

there and back without worrying whether it will or not, for half the 

price.



I think the record of my airplanes indicates it can be done.



Been thinking about inspecting clear fuel line vs my black neoprene 

fuel line.  First, I can't see all my fuel line.  Most of it is hidden 

inside the fuselage.  Based on my experience with plastic line, in 

most cases, one could not tell if it was serviceable or not by looking 

at it.  Took a hand and a pull to see if it was going to fall apart or 

not.  Sometimes the pulse line or a fuel line would do just that.



The beauty of our system of experimental airplanes is, for the most 

part, our freedom to equip and fly our aircraft the way we want to. 

Personal choice means a lot to me and I respect others freedom for 

personal choice.



However, I am still looking for a valid requirement to see the little 

bubbles in my fuel line.  



john h - Glad to hear everyone, so far, is ok down Texas way.

Buddy John, No knock taken.  Bryan and I were just showin off. It is  far and above what is required for an Ultralight. It sure was fun doing it that  way though. Much of what I do I have learned from the pioneers of UL like  yourself. Past Trophy winners have set the Bar pretty high so you have  to work hard to keep up. However, I do worry about the use of Gates Auto  Fuel Line when you run oil mix through it. Had some break down on me.

Steve B:

  

 I have heard of folks having problems with fuel/oil mix and  neoprene fuel line.  However, it has been many years ago.  Probably  have not heard of problems now because I do not pay that much attention to two  strokes and their inherent problems, unless I am going to be flying one at an  air show.

  

  

 I think this problem is like others we encounter.  Its a  one in a thousand or million thing.  I imagine today there is good  fuel line, line Yamaha Marine, that will get the job done.  Must be.   Look at the thousands of jet skiis and snow machines that used neoprene fuel  line and mixed fuel/oil in the old days.

  

 Still looking for valid reasons to look at the little  bubbles in the clear plastic line.    No one has come up with a  good reason yet.  I think it is a carry over from the early days of UL'ing  when everybody used it.  Hell, I thought we were supposed to use it, when I  got into UL'ing.

 I do worry about the  use of Gates Auto Fuel Line when you run oil mix through it. Had some break down  on me.
