If you are running stock fuel rails, you would use the Schrader valve.

Ah awesome thank you sooo much Injuneer. You are always extremely helpful.

So wiring wise I just need clarification. I have the Mallory 685 box and in the link I post they show in post #10 that the violet wire is used to ground it with that system so I assume it's going to be the same as my settup in post 47 it was with the mallory and zex dry system.

Also I have a nitrous express FPSS what your opinion on that? I hear people have problems with a lot of FPSS. Not specifically NX...

Re: Fuel pressure safety switch and dry nitrous

I have no idea what is in the ZEX box.

Running a dry system, if you lose fuel pressure and cut spark, you will lose all power. If you lose fuel pressure and cut the nitrous, you may have enough fuel to keep the engine running and get off to the side of the track or road.
