Old fuel pump had three electrical hook ups the new one has only two. Is it okay to hook up just the two or is there something else that I need? The truck is a diesel.

Hello,

Honestly, there should be two. Is it possible that the connector only has two wires going to a three-prong plug? Take a look at the attached picture. Also, picture 2 shows the wiring to the pump. There are only two. You should see a pink/black wire and a black wire going to the pump. If you have a 3rd wire, let me know the color of it. Also, if you could upload a picture for me to see the connector, it may help.

Let me know if this helps.

Take care,
Joe

When a fuel pump goes out it can do so one of two ways either it can quit and stop working or it can fail intermittently causing the engine to stall or not start.
