I have a 96 GMC Sonoma (bought it new) and the repacement fuel pump I bought 7 years ago went out. I know the shop used an Airtex pump with a lifetime warranty because I remember the warranty was the only thing that made the cost palatable. Now it appears no one (the shop/manufacturer/ or distributer) is agreeing to back that warranty. I refuse on principle to pay for a part that I shouldn't have to. Do I need to call the corporate office of the parts store that supplied the pump? I fully expect to have to swallow the labor and towing costs. Does anyone have any suggestions?
