Aluminum fuel line vs. rubber near engine

Follow along with my fuel as it goes from tank to carb and tell me if my material selections are good.

From the tank, I'm running rubber line about 8" to stainless (3/8").

Down the stainless to about 6" of rubber before and after the electric fuel pump.

Stainless all the way to the firewall.

At the firewall, about 6" of rubber to aluminum line. I've heard aluminum line dissipates heat the best.

Aluminum line on top of the intake to about 6" of rubber to the banjo pivot at the front of the carb.


1. Does aluminum dissipate heat any better than stainless or rubber?

2. I've heard that Holley fuel pumps cause a lot of noise and vibration. I'm planning on cutting a square from the sidwall of an old tire to place between the pump and frame. Any other suggestions?

3. Do banjo style pivots at the fuel bowl inlet restrict fuel flow? It seems to me sharp angles are bad for flow. Should I change to a radiused 90 degree tube off the carb?

Run a mechanical pump. The Holley electrics don't keep their fuel pressure constant. When the are run with Holley carbs they are nothing but trouble. You will get stranded a lot.

I have done everything under the sun to try to quiet them down. It won't happen.

Aluminum line will dissipate heat better. It is a conductor and rubber is an insulator.

It is best to have the least amount of rubber line with higher volume/pressure pumps. Try to keep as much of the line aluminum as possible. Don't forget to leave some flexing room in the line in the engine bay because the engine will twist a little under load.
