Fuel Line through the tunnel

Hi all, I would like to know if it is possible to change the fuel line that runs from the tank to the engine buy using the original line as a pull or snake. Is it possible to pull the original line out without pulling the engine. It appears as though there is a bit of leakage from the tunnel area. Any help would be appreciated.

Marc,

From the experience that I have had with my '74, the line is welded or brazed in at the bulkhead and on the other end at the suspension pan. You may want to check carefully on your car. The only alternative to a lot of torch work would be to cut out the line in the tunnel and replace with a high pressure plastic fuel line that would fit in the holes in the bulkhead and suspension pan. Are you sure it is the supply line or is it the return line? I think the return line is already plastic.

Good luck, Bob

Thanks Bob. I am not sure, but the return line appears to be fine. I will have to do a bit more checking, but the fumes are terrible when the car has a full tank of gas and it does not appear to be the gas fume recirulation canister in the front of the car. Thanks again for the response.

Check the gasket on your gas cap ! I saw this post on the rennlist awhile back and the owner was amazed it was something so simple. They dry and get a "set" and start leaking.
A second thought is if the overflow tube is blocked, disconnected or cracked.
Try these before going to the expense and work of replacing stuff

Team,

Thanks for the reply. I will take a look at everything you mentioned. I will let you know if that fixes the problem. Thanks again.

marc, hopefully your gas smell problem is something simple like the gas cap gasket, but if not, and you do decide to replace the fuel line in the tunnel, I have a few tips. My '66 912 is completly stripped undergoing restoration in my garage, so it was probably a LOT easier for me than it will be for you with an assembled car, but I simply disconnected the rubber lines from the hard line in the tunnel, bent back the small metal clips that hold the line in place, and pulled it out from the rear. I replaced the line with 3/8 i.d. aluminum fuel line from JEG'S-it's cheap, light, and easy to form-you don't even need to use a tubing bender-just cut to fit with a hacksaw, bend to fit, and snake it through the tunnel from the rear towards the front. Good luck

Clay, that was the initial question that I had asked, so I appreciate your answer. I was really at a loss on that one. Beleive it or not, I put a new cap on and the smell is almost gone. I am amazed at how stupid the whole thing is and that nobody (mechanics included) could figure it out.

I want to thank everyone for helping me on this baffling problem. You were all a very big help. I hope I can be the same when needed. Thanks again guys!!!
