Has anyone used steel fuel lines down the tunnel to replace the stock plastic?

Posted by: Demick Nov 26 2005, 02:44 PM

Yep. Common thing to do. Gives peace of mind - and is a good thing to do especially if you move the fuel pump to the front (thereby pressurizing the supply line through the tunnel).

Also common for 6's? Same idea, just no return line?

I would say steel lines is the most common upgrade over plastic.

I used braided SS line, however.

depends on your definition of "regular".....I'd use steel fuel line, not something found at the hardware store.

http://www.summitracing.com has steel fuel line is various sizes. If you don't buy from them, at least order a catalog.

A member here started making kits. Don't know the status right now though

I have also bought pre made kits for Jeep CJ's from Inline Tubing and they make an EXCELLENT product. (not for Porches though) BUT They also sell lengths of line and all fittings necessary to make your own. They even sell the "spring wrap" used in OEM applications

I used mild steel brake lines in 5/16" for feed and return. 60" down the tunnel and 48" in the engine compartment. I cut the flared ends off at the tank and engine ends, but left the other flares in place and connected the lines via brass fittings at the firewall.

How long have the lines been in the car with that setup?

I know I've said this enough to bore everyone...
but return lines make cooler fuel and potentially more HP in CARB'd cars!

(at the very least they can help with vapor lock issues.)

How's that setup? You're dealing with a pretty much novice
here. I've never heard of a carbureted car with a return
line.

I just did this with brake lines from NAPA. $3.49 ea

My original 6 has a return line as well as the supply line. It came that way. I just replaced both lines with Napa 5/16 and 3/8 respectively.

I bounced over to the tech write up, looks easy enough with the engine out, could this be done with the engine IN ? How painful would that be to do? Anyone done it and have any tips to share?

A couple of months. I'm still putting the car back together. (Originally the engine/tranny came out for a clutch job, and I came down with a case of DWD.)

I think if you want to replace the lines with the engine in, you'll want to use a coil of aluminum tubing and just uncoil it as you thread it into the tunnel. Somebody on the board (tat2dphreak, maybe?) used aluminum, but I don't know whether the engine was in at the time.

Trekkor- where did you get your braided SS lines, was it $$$, (I'd think so) did you run them in the factory location, how'd the project go? More details, please! Photos?
