1990 f150 front fuel tank not working
1990 F150 5.8 automatic w/ dual tanks. Issue is front tank isn't working, was working and all of a sudden tonight it's not. I added 7 gallons to front tank switched from back to front and all was good. Later tonight it wouldn't start, switch to rear tank it fires right up. When I switch it on with front tank selected I don't hear the fuel tank prime, like with the rear. Fuel gauge adjust from front and rear tank just fine. Any ideas as to what it could be.
