How much is one FPDM?

bobby1110

strait from ford $79. but i can get one through my dads shop for a little less then $70.

157dB

Might run lean and blow up.

One FPDM is not designed to hold the current of two GT pumps at full flow, they tend to fail because of thermal breakdown, one thing was powering 2 cobra 03 pumps, another is to power to GT500 or FGT pumps, there is much more current involved.

You have various options:

1.- Get another FPDM and rewire your own GT500 FP kit (the wiring schematic is on the net)

2.- Get a MDM jr that will give you more flow than two FPDM's because it does not suffer from the losses the stock FPDM does.

3.- Get an stage 2 modded FPDM that could run both FP without any thermal breakdown and loss.

4.- Get a BAP.

i have been running this set up for a year now. no problems. where is a schematic of the duel fuel pump driver set up. i cant find one at all. send it to me if you can find it. stanleyexpress@aol.com

You can check the widely known wiring diagram here on how to cascade both FPDM's, you should just add a big nice and fat power cable with its fuse coming from the main 12V on the fuse box and a relay that will excite with the current VBATT signal that comes from the inertia switch so it will still do what it is supposed to do and this relay will power both FPDM's.

The only thing I don't like of this setup is how to route the 2nd pair of FP power wires into the hat so it still will be safe and won't smell into the car.

you also have an email with the specific wiring of the kit.

best of luck.

thanks a bunch i am going to try something i will let every one know if it turns out good and i will have pics and directions to go along with it.

For $79 I would get another and call it good.
