1998 bonneville 3.8
wondered if anyone had the gm part # for the rear fuel lines.

thanks in advance

Can check this out:

Yes there are 3 lines, feed, return, and emissions(tank to canister to intake)...

Here is the problem.....those plastic lines attach to the metal lines on the sender.....the other ends attach to metal lines under the car.....If the underneath of your car is rusted, chances are those metal lines are rusted/weak.....trying to remove the plastic lines can possibly damage them, because even though there are plastic disconnects(you squeeze them), dirt/rust get'* into those disconnects and it'* hard to remove sometimes....next thing you know you are breaking lines from the sender(then you have to drop the tank) or the other end....so careful....
