I am trying to find a hobs switch for my N2O. I dont want the N2O to spray till I hit 15-20psi. I found a good fuel pressure safety switch set for 15psi, could I use that? I dont want it to mess up the switch when it sees 40-45psi either.

I should have bought a truck with an auto.

 

how about this one?

Looks to me like it will work.

 

Looks like it would work fine to me also, but you could get one local and much cheaper at Napa or a good auto parts store. Ask for thier book on adj. oil pressure switches.
