1999 Ford Windstar fuel pump

Drain out the fuel.
The fuel tank needs to be dropped down. You will find a couple straps tha hold it up to the frame. Remove one side of each one. As you lower the tank down, the fuel vent and supply hoses will need to be disconnected. The line going to the pump need to be disconnected. As well as the electrical connections.

Once the tank is out, remove the screws or ring that holds the pump to the tank. The pump module will be able to be removed at this point. Swap it out and re-install the tank. Make sure you change the filter at the same time.
