FD3S Fuel Voltage Low, Resistor

[speedjunkie]

I did the rewire mod to mine and it's great now. Before when I had only 6v to my pump the power would plateau at around 300whp on a freakin 500R, now I'm getting a lot more. I'm even using a Kenne Bell BAP and it still wasn't giving me any extra voltage before the rewire. I'll see if I can find the pic of the wiring diagram I used. It's really easy though. Wire it straight off the battery to a relay and put it in line with the wiring that's already there so it shouldn't put any more stress on the pump than what was meant to be there in the first place. Although if you don't have a relocated battery this may be more labor intensive than some other rewiring methods.

OK found it.

And here is the description...

Here is how I rewire my pump, it's a bit different then this one, but effective and simple. Even simpler for relocated batteries.

You will need enough 10G wire to go from your battery to the fuel pump area, a short 10G wire for the new ground. Some light gauge wire to power the relay, a bosch or bosch style 20-40 amp relay, and a fuse holder w/ fuse. Follow the diagram for instructions.
