So I installed my nitrous kit and my racetronix was not able to support a 100 shot so im installing a standalone fuel system with a Holley blue low pressure pump. I was wondering, with the standalone system should I have a fpss in each fuel system or just one? Also do you guys monitor the standalone system on your fuel pressure gauge? Do you have a gauge for each or do you have a way to toggle between them? I was thinking of finding a switch I could wire each sensor to then switch back and forth to monitor each system on my one gauge but I wanted to see what people normally do. Thanks

what is this in ? and how much hp that your racetronix pump can't keep up with a 100 shot ?. I did the stand alone for my nitrous so I didn't have to mess with my engine fuel system. as far as a fpss I tied in with my nitrous relay, so if I lose pressure with my stand alone it will stop the gogo juice. I hope that helps

It made 464 to the wheels with an LQ4 cnc L92s. I sprayed a 50 shot with no issue. Put in the 100 pills and fuel pressure dropped to 40. So you don't monitor your engine fuel pressure at all or have an fpss for the engine fuel pressure?

No I don't monitor the engine fuel pressure, I was putting down 490 rwhp ( until detuned ) now at 470. Running the stand alone is fuel for nitrous only. its not pulling anything from engine so just use the fpss for nitrous

Yea, i'm just worried if the engine fuel pump goes out then I won't have anything monitoring it and nothing to shut it down either while I'm spraying

you can run 2 fpss. one for each fuel system.

I'd run your n2o system through 2 fpss, a high pressure and low pressure. Try not to get the 2 mixed up, they look alike. I adjusted mine on the bench using air pressure.
