1987 Chevy K5 Blazer Fuel Pump Wireing

By | March 12, 2023



When the 1987 Chevy K5 Blazer was released, it had an innovative fuel pump system that offered a great combination of efficiency and power. But after over 30 years of use, the wiring of these systems can slowly wear down, making it harder to get the most out of your vehicle.

To keep your Blazer running like new and to ensure maximum fuel efficiency, it’s important to pay attention to the wiring of the fuel pump and make sure it is in good condition. This can be a difficult and time-consuming task, but with the right tools, knowledge, and patience, you can get the job done quickly and easily.

The first step in taking care of your Blazer’s fuel pump wiring is to make sure you have all the necessary components. This includes a new pump, relay, fuse, wires, connectors, and a fuel line. Once you have everything ready, start by disconnecting the negative battery cable to avoid any accidental electric shocks. Next, locate the fuel pump module, remove the old wiring, and replace it with the new one. Once you’ve done this, you will need to reconnect the pump to the module and connect the fuel line to the new wiring. Finally, replace the old fuse and reconnect the battery cable. After completing these steps, your Blazer’s fuel pump wiring should be as good as new.
