so what happens if one flows more than the other? the smaller pump gets damaged?

i have a modded fpdm

Boostang · October 29th, 2009, 05:34 PM

pretty much yes.. cause it will be recieving more back pressure than its putting out..

hopefully that back pressure will make more fuel come out of the injectors instead

uh.. i dont think thats how it works lol.. but we;ll see??

mounder27 · October 30th, 2009, 01:13 AM

do i need to wire in a second FPDM for the twin cobra pumps?

Boostang · October 30th, 2009, 02:56 AM

or one 40a BAP!

hardhitter · October 30th, 2009, 03:07 AM

the bap would make a fpdm upgrade even more necessary

hardhitter · November 4th, 2009, 04:29 AM

i hooked a ford gt pump together with a svt pump with the bap and i have plenty of pump left now.. i blew the bap fuse the 2nd time i tried to start the car so i put a 25 amp fuse instead of a 20

you have the wrong bap,you need the 40 amp version for dual pumps

whats the difference between the 2? would a stage 1 fpdm still be able to handle it?

One is made to drive one pump, and the 40A is for dual pumps. I don't think a stage 1 fpdm will work. You could use 2 stockers.

What about a stock fpdm and a stage 1? how would these be wired together?

I have something in my pants that costs $250 a foot, but I digress

It sounds like you're kinda finding the cheap way out of everything. Think of how much money you've already dropped on your car. What's another $100-$200 to get a proper fuel setup?

If the cheap way works then why spend extra money that I don't have? It cost about $20 to go from a 100% pegged fuel system to 75%. The hose turned out to be $6/ft.

The answer has presented itself in the form of my car not working anymore. I guess one of the fuel pumps died.

BakerFX4 · November 5th, 2009, 12:50 AM

lol... i didnt like what you were doing but....

And this talk about the 20amp BAP not running twin pumps is not true. My BAP has been wired in for a while now with my twin pumps with no problems. I know the 40amp is for the twin pumps but i left my bap hooked up when i swapped pumps and all is good. As far as if its helping i dont know but, i know i havent had any problems.

hardhitter · November 5th, 2009, 12:53 AM

I took the bap completely out and it blew a fuse in the engine compartment so i replaced the fuse with a bigger one. Somehow the car still starts but the fuel pressure on the gauge reads zero and according a datalog the fuel pump is at 95%. The fuel tank is completely full so I don't know how I'm going to fix it, assuming that it is the pump and not something else.

hardhitter · November 5th, 2009, 12:56 AM

The fuses kept blowing when i try to start the car, not while its running or at wot

BakerFX4 · November 5th, 2009, 01:25 AM

sounds to me like you are trying to N*g**r everything. Just clean your car up man. If you need something do it right or chances are it will become more of a problem that may end up costing more money and time. Now you have to drop the tank again with a full tank cause you tried to wing it.

Not trying to be mean or anything but just trying to help you minimize some of these problems.
