2000 Chevrolet Express 1500 Q&A
2000 Chevrolet Express 1500 Question: When pumping gas the fuel spills out after a few seconds. Even though not full.
Check for obstructions in the fill tube. There is also something in there that prevents fuel vapor from escaping. its part of your EVAP system. That could be malfunctioning. - big01_dram
i think there is a part to keep gas from coming out if veh. is flipped over, might be stuck. - Visitor
