The fuel pump on this vehicle is inside the tank which means the tank has to be removed to gain access to to it. This can be a fairly tough job if you live in an area with a lot of rust as the fasteners and fuel line fittings tend to get rusty and can be difficult to remove. You can remove the pickup box and get at the pump from the top but again some of the box bolts are difficult to remove and it's easy to ding up the box paint when doing it this way. I only use OEM pumps in these as I've had the best long term luck with them and it's not a job you want to do over in a few months. Look very closely at the wiring connectors at the pump and the pump holding fixture and if any of them show even the least amount of discoloration or evidence of melting then replace them accordingly. Be very careful around any fuel tank as all fuel is extremely flammable!

Testimonial: "now it wont drive very far it cuts off and fuses are blown. you gave very valuable info earlier thx for response. could it possibly be something other than the fuel pump. but the fuses are blowing each time we try to replace them the truck runs then cuts off after driving a short distance and can;t get it started back up unless we put in more fuses"

sounds like the adaptor gasket fell out of place when reinstalling. also make sure the adaptor is not cracked.
