Fuel pressure safety switch

Does anyone know what the stock setting is for the NOS FPSS?

How did you set the pressure?

Read the instructions just need clarification.

50psi and I believe it's adjustable between 50 and 70psi.

Why would they set it so high? I may need to look at another option. I am using the NX kit but this was the FPSS I found. As we all know, NX uses stock FP so basically if my pressure is always below 50PSI at WOT which it is, then my NX kit would not activate?


Someone please advise!

With the NOS Switch the system wont turn on unless you can lower the pressure with the NOS switch setting. My NX switch has a stock setting of 35psi.

The NOS FPSS is set so "high" because it was designed for a dry kit. There would be no need to have less than 50psi because the dy kit bumps up the fuel pressure. I'd say you need a NX FPSS
