1994 GMC Rally Wagon 3500 Question: fuel pump problem
how do I access the fuel pump? do I need to purchase the entire assembly or just the pump and use the old attachment parts? - Visitor
Will need to drop fuel tank and remove the assembly, some pumps come with the fuel sender also and you get no choice. Can look at RockAuto.com parts for info. - raiderron
The fuel pump may fail causing the engine to stall and not restart. Our technicians recommend replacing the fuel filter every 30,000 miles to help prevent undue strain on the fuel pump.
