Started by disconnecting the battery and pulling the Fuel Pump Relay from position 21 in the BEC. Removed the plastic panels from the trunk, interior and passenger fender to remove the GT500 harness. Removed the second FPDM and the relay.
I had previously competed the under hood work for the return style system. I added a Y-Block feed from the OEM steel lines via a Russell adapter, a feed to the front of the fuel rails from the Y-Block and a return from the rear of each rail to a fuel pressure regulator. The exiting return line port was blocked at this point.
Fore hat, harness with Walbro pumps.
I original acquired a Fore Innovations FC2 controller without realizing that with the FC2 Controller both pumps would run constantly even when only one pump was required. Running both pumps 100% of the time would heat the fuel obviously more than required and I decided to replace the FC2 Controller with an FC3 Staged Controller and Honeywell Pressure Switch. With the FC3 Controller and pressure switch the second pump would be activated when boost exceeds 5 psi.
Original FC2 Controller.
Removed the two cap screws securing the cover of the FC3 Controller with 3mm Allen wrench.
Pulled the three 25AMP (white) fuses and replaced them with 20AMP (yellow) fuses appropriate for my Walbro GSS432 pumps.
Determined the routing, measured lengths, cut and “tinned” the ends according to the Fore Innovations instructions of the 4 gauge chassis ground and power cables.
FC3 Controller mounted.
Ran the power cables for the pumps to the Fore hat. Cable length was perfect from my FC3 mounting location.
GT500 pump removed, fuel level sender transferred over to the Fore pump and Fore pump slipped in after placing a little oil on a new O-Ring.
Started with the supply line routing from the Y-Block/Check Valve to the fuel filter.
Ran the supply line almost straight down and then back to the fuel filter. Under the car I removed the OEM fuel lines and followed the original OEM path back to the tank. Had to cut the OEM rear line from the filter to the tank because some clown welded in sub frame connectors that were in the way.
Added the return line following the OEM fuel line path.
Used the OEM location and mount for the new fuel filter.
Secured the supply and return lines with Adel clamps as required under the car.
Reinstalled the front and rear plastic panels.
8AN supply and return lines heading up to the pumps. Getting the lines with fittings installed feed up and connected is definitely a two person job.
Lines attached at the pump.
