hey guys. i have a quick question. Me and a buddy were talking about having a stand alone fuel system up front, and trying to hook up a seperate FPSS for it. That meaning you would have one FPSS on the stock fuel system, and another FPSS on the stand alone???? How would you wire this up? Any schematics including the window switch, 2 fpss's and WOT switch? thanks in advance for your time guys!

You'd have to wire the FPSS's in series so if either one shuts off it'll kill the kit.

ok, so run power into the positive of the first switch, out of the negative/ground terminal to the positive of the second switch, then run the negative/ground terminal of the second switch to the relay??

I've never used an FPSS, but I assume they're just a switch operated by pressure right? IE: if the pressure drops below the threshold the circuit is broken? If that's the case then yeah, that's how you'd do it. And your WOT and window switches will be in that circuit in a series as well.

badass man. I guess I didnt think it would be that easy! shows what i know, LOL Overthinking is a bitch! And yes, its just a switch, that if fuel pressure dros below a set value, it kicks off the system. Basically a normally closed switch, that when pressure drops, it opens the switch, killing the circuit.
