[Mark Umfleet]

It is a street car.

why is aluminum bad on a street car? i have used it on my 67 tuneport camaro for over 12 years without a single problem. if i remember right i just used double clamps at every hose connection. tpi runs about 45psi. the holley avenger efi runs low 20 psi so i was just planning on doing the same thing with 1/2 aluminum liine on my 71 camaro.

Well, I owned my 67 RS Camaro since 1983. I used mild steel hardline in the past. I also tried braided line. The problem with braided is that it only lasts a few years. I never thought about aluminum line, but I thought it was to soft and inexpensive. The problem is that you can't predict what is going to be on the road, it could be gravel, nails, and a friend hit a cylinder head. Tore up his 3 piece rims. Actually,none of my racing friends use aluminum line either. I seen people cut corners on lot things. Just think about your safety first. Actually aluminum fuel lines are not DOT approved.

On my 67 RS Camaro, I plan to use stainless hard lines with my LS3 416 with Harrop 2300 Supercharger.

a lot of OEM under car ac lines are aluminum. they don't fail very often. I've never had a problem with aluminum fuel line either.

I have heard it would crack so I never used it. I always went with the braided line.

I know a lot of people use aluminum line in their projects, but I personally would not. I am building a tube chassis 70 Camaro drag car right now and will be using braided line the whole length of the car. It is definately more expensive and weighs more but safety is always first in my book. I have seen multiple cars at the track put holes in the line during a burnout and run down the track. The one that really sticks out in my mind is a car doing a burnout must have kicked up a stone and split the fuel line running down the rail and caused a huge fire. I know this was a rare case but it does happen. This is just my take on this, good luck with the project.

I ran aluminum 1/2" the length of my car and never had a problem. Mine wasn't flared as I used conical fittings. I never experienced a leak. A couple things come to mind. If you are not running teflon lined hose, how do you feel it's safer? Those things spring leaks left and right due to detioration. I'd rather have a fuel leak due to running over debris than detioration. At least it's not a surprise. Next, debris is just as likely to take out a hose as it is a hard line. Lastly, hoses are known for smelling up your garage.

I would recommend that no matter what material you use, that you think about what routing on the car you are going to take. You want to protect the fuel line from debris and damage. A simple cover made from 22 gauge steel or 032 aluminum covering the fuel lines in high risk areas weights very little but can offer tremendous protection from road debris.
