Fuel lines

I will be running new fuel lines on a Corvette frame off restoration. I have 3/8 stainless line, but someone suggested using 1/2 aluminum. Would anyone know the advantages to aluminum line? The long block is built and is only 9.5 to 1 comp. with vortec heads and the shop that built it estimates 355 hp. I will be using some sort of fuel injection setup, but I haven't planed that part yet. If I use the aluminum is there any special considerations?

Most Fuel Injections of late require a return line.......so you will need 2 lines.

Stainless steel is very hard to double flare

Just adding my 2 cents........

te large line is only needed by drag cars with multiple carbs and lots of fuel consumption, for your intended use the stainless line would be more durable, corrosion resistant etc, it is harder to flare and bend but it will last the life of the car.

Ever wonder why cars don`t come new with easy to use aluminum fuel lines? The feds say no.

BOBCRMANs right it is hard to flair, but with good tools it`s easy
enough. and lasts forever,and cleans up nice. The 3/8 you have will handle anything you can run on the street. Good Luck.

if your going to use fuel injection im not sure if Id run aluminum line, with injection there is alot more fuel pressure needed, Id check the burst strength first....and 3/8 line is plenty...

Fuel line size

The fuel line sizes will be dependent on the pump and regulator you use, not the application. Different type of pumps will require different line sizes based on how they are designed. Make sure to check with your pump manufacture before installing the lines.

69 Vette...

I re-built my 69 Vette, originally a small block car. It has 2 fuel lines, a 3/8" supply and a 1/4" return. Big block car only had the supply line. Aluminum is easier to "play" with, but the stain stl. is way more durable! Yes is is a pain to flair but not possible. OR you could buy the lines already bent and flared ...not that much more (the way I went ...& P.S. ...Stick with S.Stl.!!! The ONLY WAY TO GO!) ...My 2 cents! ...Mark
