REFLECTOR: fuel line

[Jim Agnew]

The best and longest lasting fuel lines and fittings are Aeroquip stainless steel braid over Teflon hose.  The question you must ask yourself is do you want the safest and longest lasting installation or are you willing to settle for a a less adequate but usable installation.  At some point you reach a less than adequate and possibly dangerous system.  Only you can determine what you feel is adequate and if you are unable to evaluate the options seek advice from experts.  The factory is a good point to start as well as well known major hose & Fitting suppliers like Amazon Hose.

I built my plane using the engineering philosophy of "bullet proofing" or eliminating as many failure points as possible. This costs time & money and that is why I chose  the high end Aeroquip stainless steel braid over Teflon hose & fittings.

Subject: REFLECTOR: fuel line


In an atempt to change the subject...
I've got questions about fuel line.
The 2000 vintage instructions show alum tube out of the strake changing to hose near the sump.
I've seen planes that run the alum tube all the way to the sump.
I know of guys that have run Aeroquip 601 from the strake to the sump.

At $25 a piece the Aeroquip fittings are pretty steep.
Is it worth it to not have to bend the tubing / flair ect?

Splicing in the tubing looks like the easy way to do it.
Any problems with the splice?
How is the best way to do the splice?
I know there are tools to put that funny little bulge on the end of the tubing, I don't have one...

Is there a potental problem with alum tubing all the way?
Would vibration be a prob?
Is there a fundamental design reason for splicing the tube to hose?


I'm leaning toward all alum tubing...(based solely on looks)  But I don't like making changes to the kit when I don't fully understand the reasoning for the way it is.

Anyone have fuel line problems either way?
