How to Wire a New Fuel Pump

Installing any auto part can seem like a simple job until you have your whole car torn apart and realize everything is not right. Many a shad-tree-mechanic get the shock of their week when they pull out a fuel pump only to find the wiring to the fuel pump assembly is different than theirs. The first reaction is of course …rage, those sons of $^&*#^’s but this may not be needed. Most modern cars use similar set ups for fuel pumps or updated wiring harnesses that are a simple 5 min wiring job.

Now before you start any job it is essential for you to know that the job is not out of your knowledge range. Just keep in mind this is a machine that will be hurling you down the road at enormous speed. It is not a great idea to be guessing at how it works. So it must be said, if you don’t know how…let someone who does. Oh and don’t ever smoke while installing a fuel pump. When starting the wiring job, determine what colors your factory wires are from the factory harness. Once you have them you can find a wiring diagram usually supplied by the fuel pump supplier or on their webpage under the help section.
