? About aluminum tubing and FI pressure

[Rallye455]

Has anyone used aluminum tubing for their fuel line in a Fuel injected application? I already have 1/2" aluminum tubing run and really dont want to redo it out of steel or stainless. How well will the aluminum hold up?

I don't think you'll have a pressure problem. If it's been okay so far I say keep it.

What is the wall thickness? Do you know if it is seamless?

If you go to mcmaster.com and search for aluminum tubing it will give you the specs for different diameters and wall thickness. Take a look.

But the tubing will easily handle 100psi.

Think about earls brake line fitings... they are aluminum and handle 2000psi.

I think you are fine.

All my fuel lines are aluminum. .035 wall 6061. It's rated to 1700 psi.

Almost any aluminum tube I can imagine is extruded seamless- it's easier to make aluminum seamless than it is to do something like erw on steel.

Remember that A/C systems w/ 1mm wall tubes (.039") run discharge pressures of 300 psi, and aren't supposed to until at least 3x that pressure

You might post this same question over on Lateral-G.net. I know that Mark Bohlen of Bent Custom & Performance posts over and he might give you a better reply. http://bentcustomandperformance.com/index.html

Consider the fact the the stock LS1 cars have plastic fuel lines that run the length of the car.

I think the least of your worries would be aluminum line not being up to handling the EFI fuel pressure.

Plastic can withstand rocks and other debris that you might run over, while aluminum is very soft. Personally, I would do steel or stainless line before I would do aluminum. I really wouldn't worry to much about the pressure, because the manufacturer has already solved that problem for you.

light airplanes which i am very familair with and most of it is 5052-O. It is easily bendable and weldable, good to 1500 psi or more. Hydraulic systems are normally around 1000-1200 psi, so you should have no problems at 60 psi.

Thanks for everyones help. I figured the pressure would be ok, just not sure about longevity.
