I have a 5/16" fuel line front to rear, which I am planning on replacing with the 3/8" line. I had my car in to get some adjustments to the carberator today and they recommended the upgrade to the larger line based on the larger engine and carb. They mentioned that they have seen where the fuel line is routed on the outside away from the exhaust to prevent heat problems and vapor lock. My question is are the 3/8" lines prebent to accomodate the different routing, or do they follow the same bends and turns as the 5/16" lines? I did notice that the existing line does run within a few inchs of the muffler and I believe the original single exhaust for the 6 cylinder ran on the other side away from the fuel line...

The rotted 3/8" line I took of saturday ran along the inboard side of the framerial from the gas tank, twisted around the front spring perch, then ran up the side right at the rocker, and then along the top of the subframe to the motor.

That seems to be the same route that mine goes so there must not have been a difference between the two line sizes as far as routing.

Did you get the new lines yet? If so, do the have the stone guard protection on them and where did you get them from?

Thanks.

I'm gonna order them direct from Inline Tube. They do have the springs on them. Still undecided mild steel ($65) or stainless (99)

Will probably go mild steel then clearcoat em. Gonna run 2 lines (for future efi return line) and will have to "adjust" them a little so they will fit side by side, been told working with stainless tube is a "beetch"!

Jim I tried bending and flaring my own stainless lines. Forget it!:angry: Bending it was bad enough even with the 18" bender.:rolleyes: Now flaring it was a total joke.:clonk: But if your planning to get pre-bent lines that all you have to do is some minor tweaking and bold on got stainless. That's what I did for the rear brake lines. I tried cleaning up the front brake lines and clearing them, but after about 1 1/2 yrs they started to show some rust from underneath. As for fuel I decided I didn't want to run steal and I was to cheap to pay for stainless so I made my own from aluminum for @ $22 and still had enough to do my friends Nova.:thumbsup:

I switched over from the 5/16'' fuel line to the OEM material 3/8'' fuel line on my Camaro. The new 3/8'' line was pre-bent to fit the same route along the passenger side body and to the outter side of the sub frame rail then back over to the engine compartment. The only place where you might have a problem with vapor lock (but not likely), is where the fuel line runs close to the exhaust.....just before the main crossmember.The clearance issue will change depending on if you have Headers vs. the stock exhaust...which would change the clearance between the header and the frame rail. It did come that way from the factory, so obviously they did not see this as being a problem with the factory exhaust set-up. If you feel that there might be a problem with vapor lock because of the headers being too close to the fuel line, you can always wrap that part of the fuel line with heat tape. Other than that, I don't see it being a problem.

I got my new 3/8'' fuel line through Fine Lines in Ohio. I've been pretty happy with them.

fuel lines in stainless are fine however brake lines in stainless tent to leak at the double fare ends. the stiff stainless material isnt as maleable as the OEM material.therefore it doesnt create a good double flare seal.it is possible to get it to work.but sometimes it takes quite a bit of tightening to seal.
