Schematic question for Aeromotive Fuel Pump Controller

94GT427 · #1 (**permalink**) 08-09-2010, 06:14 PM

I have FAST XFI with an Aeromotive A1000 FP. Come to find out I really need to add a fuel pump speed controller because of the altitude I'm at, my fuel vaporizes too quickly on hot days.

Has anyone installed/added an Aeromotive 16306 fuel pump speed controller to an existing standard Aeromotive fuel system that is controlled by the FAST XFI? Just looking for a schematic to make it right.
Thanks

This has been done by several customers.

There is no specific schematic for it.

The fuel pump controller is looking to be triggered by +12v. The XFI supplies a ground normally to turn the fuel pump relay on. So you would have to use a relay. Let the XFI trigger the relay, which then sends +12v to the fuel pump controller.

Here is a link to the instructions on Aeromotive's website.

Your relay would go on the 16ga red wire.

Thanks Matt.

My fuel pump relay is in the back of the vehicle currently. I have a 10ga +12v battery and switched +12v trigger to the fast -12v input, typical fuel pump and relay wiring. I would remove the +12v battery from the relay and connect it to the fuel pump controller.

Next and do you see any problem with splicing into the +12v battery power that connects to the speed controller to provide power to the relay that use to have the +12v battery wire? Then run the +12v 16ga red "PWR" trigger wire from the relay to the fuel pump controller and leave the trigger wires for the FAST alone?

I would then only have to run my tach signal and over ride wiring to the front of the car. Does this all sound about right and I hope I made this clear.
Thanks again.

I read it 3 times. I think I got your meaning.

Basically leave the XFI 12v switch and main power alone. Just take your current fuel pump relay and use it to power the fuel pump controller instead of going straight to the fuel pump.

Here, a picture. I thought I had explained that just clear as MUD.

I drew a schematic to show what I am thinking is a good way to just add this fuel pump controller in to my current setup. Comments, because I am not 100% on this sort of thing.
Thanks again.

That should work great!
