Default fuel line

What is everyone using for fuel line...aluminum, stainless steel, braided, etc. and what are the advantages and disadvantages to each. Also, the link below claims to be good to 135 psi. Could a rubber hose really work?

I am using 3/8" stainless between the Tank and engine, then AN fitting and SS Braided hose as needed to connect all.

If you get the correct EFI rubber hose and clamps, it should be ok.. as with some and many OEM fuel system, they use rubber or poly lines. Just make sure it is rated to handle the high PSI of the pump.

The stock Fbody fuel system runs at 55-65 psi at the fuel rail. The Corvette filter/regulator (must have been made for swaps; the Corvette came afterwards) supplies the above pressure. Your fuel pump should be running at something higher, like 80-90 psi.

repro stainless 3/8 fuel supply line, cut off the hose barbs and used Swagelok tube-to-AN compression fittings. For the soft lines on each end, I used Aeroquip -6AN socketless rubber hose and fittings, rated for 250psi operating pressure. The Aeroquip socketless hose is great stuff--reliable, no bling, no overbraid hiding rubber deterioration, and the fittings just push into the hose without any assembly or tools.

I used the vette combo filter/regulator near the tank and 3/8" aluminum tube from Summit along the frame rail to the engine. I used a 3/8 black plastic hose to protect the aluminum tube along the frame rail. Then Russell AN fittings and SS braided hose as needed to connect all. I did have to get a short 3/8" tube from Street and Performance made to insert into the filter/regulator.

I used braided stainless lines from the tank to the fuel rail. Factory type quick connects on the pump and regular an fittings everywhere else. Working great so far.

The Auction is for one foot of hose.

Rubber hose would work fine but I wouldn't do it. Just bend up a set of steel lines. It's a bit of a pain but will look beter in the long run.

Plastic fuel line from tank to fuel rail. All line and fittings available aftermarket. Looks just like new cars fuel lines. Just heat up the line and shrink it on to the quick disconnect fittings.

If you use aluminum be sure that it is secured so that it won't vibrate. Particularly where connections are made. Otherwise over time the alumnum can fatigue and develope cracks. Personally I would avoid it.

NHRA rules don't allow more than a foot of rubber line on a car... Something to think about.


I'll be using all stainless braided.
