914World.com _ 914World Garage _ fuel lines: feed or return?

Posted by: double-a Mar 25 2005, 12:07 AM

i installed new heater hose tonight, and while i was under the car i noticed a kinked fuel line. it's one of the plastic ones, kinked right at the firewall. it doesn't leak, but should i be worried? which of the two lines is the feeder line, and which is the return? the car is stock, no modifications to the fuel lines.

The return is the smaller of the two (driver's side IIRC). If either is kinked, I'd just replace them both with some steel (5/16" return, 3/8" supply) brake lines and not take any chances on damaging a fuel system component because of back pressure, or overheating the fuel pump (not to mention a crack developing at the kink someday).

Pretty good article on replacing fuel lines can be read/viewed at:

thanks, that's good info. i checked out the engine bay this morning, and the fuel line that is kinked attaches to the line that comes from the driver's side. the other plastic line that is not kinked attaches to the passenger side fuel rail.

also, both lines are the same size as far as i can tell.
