Aeromotive fuel pumps.

I have to start thinking about fuel system soon. I was looking at the Aeromotive 5.0 brushless fuel pump. The pump is located here: https://aeromotiveinc.com/product/b...spur-gear-pump-with-variable-speed-controller. It's a variable speed controller but the PWM from the FPCM cannot be used, that is on a scale of 0-12v (theory, no real data in the FSM or online to support this). However Aeromotive says that a voltage source from 0-5V would be perfectly acceptable.



What sources would be acceptable for 0-5v? Hellcrate doesn't want you touching the harness on the throttle body (I am assuming a dirty signal condition). What alternatives are there that won't create a dirty signal condition? Or do I scrap all this and just put the relay on a 12v switch and have it going 100% all the time, it's a race car so I don't need to worry about it being on 24/7.

There is also a Weldon pump that could be great as well. Leaving it on just for racing on a 12v switch as well: https://www.weldonracing.com/store/2345-A-p56104058

Any thoughts would be appreciated.

7.0 gpm brushless on 12v. What the hell is a TPS. 😂

that is a serious set of bulkhead power and ground distribution studs thank you for the input

Don’t mistake those small gauge wires as something from the hardware store. They are some kind of high cap super wire according to Aeromotive.
