Hello I will help you with your question,


The Fuel pump is powered through the ECMB fuse through the fuel pump relay. The power to turn the relay on is supplied by the Engine control Module





The lower left fuse is the ECMB



Let me know what engine you have and I may be able to help you further with your question


Thank you

My truck is not a four-wheel drive. It is a V6, 2.8 liter engine. Where is the fuse box located? I think I asked the wrong question. It is the fuel pump fuse that I am trying to replace. I have the part, but don't know how to find where it goes.

The part has a small black rectangular top with four prongs sticking out of one end.

There is no fuel pump fuse per se.. The ECMB supplies power to the relay which sounds like the part you are describing. The fuse block is under the dash on the drivers side, the diagram I posted is for a 2.8L


The fuel pump relay is located at #1 in this diagram which is against the firewall on the drivers side of the engine compartment





Let me know if this looks like the part you have.
