Electric Fuel Pump


In the midst of changing from a V-belt accessory drive system to a serpentine belt system, it was discovered that the mechanical fuel pump interferred with the mounting bracket for the power steering pump and A/C compressor. The choice was to hog out some of the mounting bracket or come up with another means for moving fuel. I had an old Holley Red electric fuel pump sitting around, so I decided to remove the mechanical fuel pump and install an electric one.
Step one - find an available fuse. I'm not running the fuel pump directly from the fuse box, but am installing a relay. Hence, from the fuse box I only need a couple amps from the "run" circuit. I picked up this fuse "tap" from AutoZone. It plugs into any fuse position, provides a mounting socket for the fuse that it replaces, and then provides a position for a second fuse and wire to the new circuit. I tapped into the fuse for the dash gauges.
I mounted the relay for the fuel pump in the battery box under the floor board.
I don't really like where I mounted the fuel pump and may end up moving it. However, this was the easiest and only location around the gas tank that had sufficient space to mount the fuel pump vertically (without constructing some custom mount). This is located behind the fuel tank, in front of the rear bumper and towing bracket - so susceptible to rear-end collision. I really need to construct a better mounting bracket.
The original fuel line was copper hard line. I changed to braided stainless steel 6AN hose and fittings. Coming from the rear of the truck directly to the carb also freed up some clutter around the front of the engine.
Here's a rear view of the installed fuel pump. Although this works, it is extremely noisy (a common complaint with these fuel pumps. When I relocate this, I'll need to add some rubber isolation to quiet it down.
