Man, this is getting irritating trying to find the right stuff. talked to another friend today that used to race dirt track (the cars with the big wings on top) and he said they ran regular rubber fuel lines, only used braided in certain spots.

I can only find the 1/2 steel one place so far, and they only sell that size in 6ft lengths, that makes it a hassle and would require a coupling, I don't much like that idea.

8an is 7/16" ID. that's real close to 1/2".

anyways, I had a novel idea. call edelbrock, ask them. (actually my friend recommended that, he said they made the carb and they know their stuff, go with what they said.)

In the end it is this:

Mechanical pump, 110gph flow rate
pressure regulator to make sure no more than 6psi at the carb, 5-6 is max recommended
8an braided from hard line to pump, hard line to fuel cell etc.
They said no need to run return with a mechanical pump
Also said aluminum was fine and they prefer to steel because easier with fitting etc., they DON'T recommend braided for along the frame because it hardens and will need replacing.

Also he said 3/8 was plenty until about 600hp, and return, if I did an electric, would only need to be 5/16.

I appreciate all the advice guys, you can see with so many different opinions and takes on it I had to make a decision. I know those who disagreed will be miffed, I'll buy you a beer if you're ever around.
