Default fuel line replacement

Has anyone ever replaced the fuel feed line? (the one with the check valve)
I didn't have a lift to allow me to access it, so I decided to let my mechanic (good friend) replace it. He just called and said they would have to PULL THE TANK (SIX HOURS by book!!! ) to be able to install it.
Anyone done it without pulling the tank?

If you are talking from the fuel filter to the motor. you should be able to do it with removing the tank.

I just looked it up in the Service manual. Drop the Exhaust, drop the heat shield and the fuel line right there. I have a lift if you want to drive down this way

Dang...I really appreciate the offer. I took it to my mechanic because I didn't have a lift, and with the car lowered, I couldn't get it high enough to maneuver under. It looked like it would be a "crowded", but pretty straight forward job with the exhaust removed (the mechanic GUESSED 1 hour) but he called yesterday and said he would have to remove the tank (a six hour job at $70hr)
This is the first time I've taken my car to a mechanic in probably 5years because I've always done all my modding myself, and NOW I REMEMBER WHY!!!!
I really appricate the offer; I REALLY need to get a lift

I have had my fuel lines replaced completely. I now havve the RSI Dual-Pump system in my driver's-side tank. All the new lines go from there, up the tunnel, and up the firewall.

I bet you had to remove the tank for THAT install
Looks good

That "access hole" in the frame in photo three is what is the issue. I'm having to replace the line that has the check ball in it (it went bad) which has a "T-fitting" in it, and you can't come from the bottom, so it has to be run DOWN from the top. definitely a PAIN!

Nope! The tank was never pulled. My mechanic is very good, and had it up on a lift. He is the one that took all the pictures for me. He is Joey Cartee, at Corvettes and Classics, in Greenville, SC.

Clif: You have those beautiful stainless flexible lines, but the problem here is that Blow Torch is replacing a factory molded black nylon fuel line and it will only bend a small amount before it buckles and kinks.

Short of dropping tank, etc, the ONLY thing I can think of that might work would be to cut/splice in a section of flexible hose where needed to go up through, and over that frame section. Just gotta keep in mind that this is a 58 psi (nominal) fuel line and that any splicing must NOT be done with hose and screw clamps directly onto the nylon line. I'm thinking maybe some compression fittings of the proper size, that have hose barbs, might work. Then the rubber hose is pressed on over the barbs and clamped. That would hold the pressure fine. Maybe Russel or someone else has some splice fittings that could be used to create the necessary length of flexible hose (stainless or fabric covered). That would solve the problem. Food for thought.
