Sounds like the fuel vent line is clogged.


do u have to get a new one or can u unclogg it


Here's what the vent valve looks like - http://www.ebay.com/itm/Dorman- 911-001-Fuel-Tank-Vent-Valve-/130435514599? pt=Motors_Car_Truck_Parts_Accessories&fits=Year%3A1998%7CMake %3AGMC&hash=item1e5e9000e7&vxp=mtr --- The vent line should be the small black rubber line that plugs into it.

Sounds like your tank is full and your gauge is reading wrong.
