Fuel line size
As my sig is saying, I'm doing a complete rebuild and even though my budget doesn't allow me a new engine right now, I would like to make the car ready for a 1000hp engine. So my question is, should I put back my stock fuel lines or would it not be big enough for the new engine to come and I should look for a large line? If so, which size should I look at?
BTW: That engine will probably be a blown 477ci BB but it might change like eveything did in this darn project.

Re: Fuel line size (Lohkay)
1000HP? Sounds like a pretty fun, but expensive, project to me! :D I wouldn't even consider using the stock 3/8" fuel line on a 1000HP motor. 1/2" is as small as I would go. :cheers:
P.S. You should note that 1/2" aluminum and 1/2" stainless fuel line are not the same. The 1/2" aluminum has thicker walled tubing than 1/2" stainless whick makes the aluminum's inside diameter smaller.

1/2 " stainless on my 68' Camaro.
No matter what I do, I WILL NOT HAVE TO REPLACE THAT LINE!
Plus, more gas=a little cooler temps to the carb/FI.

Don't have one, but maybe you can get a "trick" package deal if you don't fab it yourself.
IMHO, it will all depend on the OEM's fuel system requirements.

Re: Fuel line size (ALLTHROTTLE&NOBOTTLE)
I went with 5/8". I wanted to go 3/4, but we didn't have room. The common misconception is that the larger line is needed for more power. Not nescesarily true. You could probably get 1,000 HP out of a 3/8" line but you would run into cooling issues. The larger the line, the better the fuel flows away from the engine which therefore keeps the fuel cooler. Hot fuel = bad. I also suggest you stay away from solid aluminum lines. They crack pretty easily when bent. I actually used some wound stainless that I got from a Boeing supplier. Yes, you read that right - it's airplane hose! Good to well past the 50 psi I'm running. Just my 2 cents. The bigger you can go, the better...
