I have a 1989 Horizon that I cant seem to get started this year. I checked the fuses but they all seem fine want to know if its a hard job changing the fuel pump thats in the tank. Or if any one has any other ideas that I can Ck before I get into this big project. Ok Ive changed the relay and the fuel filter. And neither of those worked any suggestions and an easy wasy to remove tank and get to this fuel pump
