Fuel lines
 

My 944 N/A, has developed a leak from what I think is the pressure return line. It is with 2 other fuel lines (?), at the elbow, by the torque tube, in the rear right of the car. I thought it to b e the pressure return line as when the car is shut off, I can hear it bleading down for a few seconds...Now my Question....Am I right as to what line is leaking, and what kind of parts replacement cost am I looking at. Also, can I use a inexpensive, high pressure fuel line as a replacement on all 3 lines....Many thanks Paul

Sure you can just use high pressure fuel lines and the old fittings and make your own.

Thanks
 

Thanks Doc....But the 3 lines, are they fuel supply, fuel pressure return, and the small one being a tank vent? (It was the small on that collapsed at the elbow).
Thanks.....Paul

More than likely you are seeing the charcoal canister vent line. There shouldn't be any fuel in there, just fumes (emissions thing venting back to the tank).

Thanks again Doc........That makes sense.
