First, remove all FI components.
Remove the FI wiring that plugs into a 5 point connector on the left rear of the relay board. Do not remove the 12 point connector on the right rear of the relay board! Remove the original fuel pump.
At your local AutoZone buy a Holley electric fuel pump rated at 7psi of fuel pressure, they cost $50.
While you are there buy some red 14 gauge wire (roll) of electrical wire 12 feet will be enough. Buy a throw 2 pole electrical switch $5. Then buy a 20 amp fuse with its associated wiring about $3.
At this point you are halfway done.
When you remove the old fuel pump you need to plug the fuel line that returns fuel to the tank. You have several options. You can remove the fuel tank and mount your new Holley pump right below the fuel tank or mount it where the original one. Either way if you can drain the fuel out of the tank for this procedure. Your new Holley fuel pump will have a red wire and a black wire. The black wire bolts to the chassis, the red wire goes to pos+ side of the battery. Now on that red wire I solder the 20 amp fuse and that on off switch. BTW on my last 3 914’s including a 75 I mounted the holly pump under the fuel tank which required me removing the fuel tank. Running the red wire by my seat to a switch with the fuse on to the pos+ of the Batt. See part 2
