How to Replace a Fuel Pump on a 1987 Chevrolet C10

The 1987 Chevrolet C-10 pickup was one of the first years with a fuel injection system, called the throttle body injection or TBI system. These motors use a fuel pump mounted in the engine compartment to control the fuel flowing from the tank and into the fuel injectors. When the fuel pump goes out, the fuel injection system won't be able to function properly. To fix the problem, you have to replace the pump.

Tools Used: Flathead screwdriver, Open-end wrench set, Chevrolet fuel pump in MAF tool J-26987, Replacement fuel pump, 3/8-inch ratchet and socket set

Replace a Fuel Pump

Pop the hood. Remove the air cleaner by untwisting the wingnut on the top of the cleaner. Pull off any adjoining hoses to the air cleaner using the flathead screwdriver. Disconnect the throttle cable, transmission cable, throttle rod, and return spring using an open-end wrench.

Unbolt the air conditioning compressor brace from the engine using the 3/8-inch ratchet and socket and disconnect the fuel line from the brace. Use a flathead screwdriver to pull off the hose clamps on the fuel filter, then pull off the filter. Remove the hose clamps on each fuel injector nozzle using a pair of wrenches.

Remove the fuel pump from the engine using Chevrolet fuel pump in MAF tool J-26987. Install the replacement fuel pump using the same tool. Reassemble the rest of the fuel system in the reverse order of disassembly.

Tips & Warnings

Never smoke or have an open flame nearby while you're working on the fuel system of a vehicle.
