Fuel pessure switch

[ON THE HUNT]

I'm looking for a fuel pressure switch (Hobbs type) 5 psi. or lower. Normally closed or normally open, it does not matter.

Nitrous Oxide Systems (NOS) has several adjustable pressure switches. #15660 is 1-7 psi with N.O. contacts. #15670 is the same with N.C. contacts. They sell for around $35 (Jegs, Summit, etc)
