Did the exact same thing a couple of years ago. Buddy and I were welding some floor pan cracks and hit the nylon line. Made a mess, repaired the line and ran it for one event before replumbing the whole fuel system.

Factory fuel line routing on the 4th gens is a hazard by design. The factory hard lines run in the trans tunnel, and all it takes is a bent torque arm to wipe them out. I say this, because earlier this year I had a bent torque arm rub hard into the trans tunnel where the factory hard lines used to be. It rubbed so hard that the factory mounting boss for the line retainer got ripped off and put a small hole there, can't imagine what would have happened if the factory lines were still there.

I ripped it all out, ran liquid-tite high temp conduit from the rear bulkhead, thru the cabin along the passenger side of the trans/dshaft tunnel, through the firewall. I then snake 6an PTFE (rated for >1000psi) through the conduit and assembled the fittings on each end. After that I cut the tube off of the factory fuel rail off and had a 6an bung TIGed on; the return rail had the the factory FPR replaced with an Aeromotive with screw-in 6AN fitting set to the factory FPR. I then had a new fuel pump get 6an steel bungs TIGed on the end. All in all I have a total of 6 fittings for my entire fuel system, all completely isolated from me along any undercar debris or rotating/moving parts.


I don't want to worry about burning to death in a early '90s pony car. There are better ways to go out in life.
