Good evening gentlemen,
I have a 51 F1 with a 350 sbc, it was built before I bought it, and im having trouble with the oil pressure gauge.
When I first got the truck, the oil pressure didn't seem to read anything, I put it down to a faulty switch, as the engine ran fine, no knocks or rattles etc.
Then the switch started leaking, so I thought I would replace it with something that actually moved the needle.
So I bought a new switch from demon Tweaks, after first checking the gauge itself was working, shorting the wire to earth had the needle moving.
I bought this one https://www.demon-tweeks.com/uk/sear...y/q/lmatim097/ but still have no movement on the needle.
I have measured the pressure using a stand alone pressure tester and its fine. The truck was converted to 12v before I bought it , im not sure what kit/loom/trickery was used.
any advice would be so gratefully appreciated.#
