Im looking to buy a fuel pressure switch for the nitrous kit i have coming. Ive looked up a bunch, and I need some help deciding. The main thing I need to know has to dowith the adjustable psi. there are ones adjustable from 4-7psi,and then ones for 25-50psi.so which onewould I need.I dont wanna buy the wrongone on accident. thanks!

 

4-7 psi would be for a carburated engine (like the stroker smallblock in my 68 camaro w/250hp NOS kit) 25-50 psi would be for a fuel injected engine ..like in the G...much care to be used in the design of any nitrous system..I have played with them for 25 yrs and have a few lessons learned in this dept.

good luck
