Fuel Pump Conversion on 1984 Ford SVO
#3

An 85-97 Mustang 190 lph fuel pump can be used in the tank of an 84 SVO and then you can remove the external pump. That is much cheaper than replacing both pumps. Your fuel guage is not affected.

You can get a pump and bracket from Ford if you like, or you can get the Walbro pump from http://www.autoperformanceengineering.com/ (part # FPF001) and get a bracket from a salvage yard from any late 80s or early 90s Mustang. Then you'll need to replace your fuel filter with a Ranger filter because it has longer inlet and outlet pipes. Just connect the fuel line from the tank to the Ranger filter and remove the external pump and the short fuel line that is between them. Tie up the wire harness from the external pump so it doesn't hang.

Next you need to replace the resistance wire that is inline with the fuel pump ground wire with a good wire. Look under the carpet in the hatch. The wire harness that comes up through the floor is the pump and level sensor harness. The pump ground wire is the one that changes size from a thick wire to a thin one. Cut the wire where it is thick, on the pump side of the thin wire, and solder another thick wire (like 16 guage, no thinner than 18 guage) onto it. Connect the other end of the new wire to a good chassis ground. I connected mine to the green-painted ground screws near the tail lights. You'll have to remove the rear interior panel to find them.

If you're in a rush you can install the pump and do the wiring later. But you'll want to get to it soon or you may run lean at high rpm and boost.
My totaled 84 SVO had: ported big-valve head, roller cam, front IC, BPV, E6, 3" exh; 259 rwhp, 331 rwtq at 19 psi.
