If you are bidding on my Fuel Pressure gauge, you will notice the gauge is at 1psi. This is after I tested the gauge to see if it read pressure and it does. The needle slowed to 1psi when I took the photos for the ad.
I just picked up the gauge now and noticed it returned to zero psi as it should. I am unable to add any more photos to the ad unfortunately so bidders may think it isn't working properly. This gauge hasn't had cycles of fuel pressure in decades and I'd imagine just needs to be used again to loosen up.

So the gauge works and returns to zero as it should. Please bid if you are interested thank you!
