Thread: Drop Fuel Tank

I have problem code for evap pressure low. I put on new gas cap. Problem still there. Pulled fuel pump. O-ring might have not been sealing. Problem I think I might have is there are three lines going to fuel pump. I think they are 1. fuel delivery 2. fuel return 3. evap. Found that one line isn't hooked up to anything. It is about 14" long and shaped like a u. It has the quick release fittings on both ends. It was hooked up to one of the three connections on fuel pump. All three connections on top go toward drivers side of car. The line in question went out toward drivers side about 4 inchs, then 90 degree bend toward front of car for about 6", then 90 degree bend toward passenger side for about 4 ". I can find no other line unhooked. I went to GM and got a schematic. It does not show this line. I do not know if previous owner had this out and just put something there that does not belong. I have fuel leak only when filling tank full. Can not tell for sure if gas is coming out this hose or was coming out from possible o-ring problem on fuel pump. Any help would be appreciated.

TurboTodd,

I'd suggest you start a new thread with your problem. You'll most likely receive more hits/suggestions. I took my fuel pump access cover off just last night and did see the three lines you mentioned above. I really wasn't concerned w/ the fuel pump though so I didn't really look around in detail, just blew all the dust off the pump.

I did see in another thread someone had a similar problem with a line that just ended to the air.

Thanks, I will start new thread. I have never started a thread but will see if I can figure it out.
