Water pressure gauge

[dykstra]

New impeller, backflushed everything, blew air through the water line from side of block to water gauge, ran motor, water is going through water line. I am wondering if the gauge is shot.

Does the guage needle move at all?

Connect the gauge to a small regulator, then turn up the air. I have one I use for my airbrush- has a fine-gradient gauge on it and will adjust by 1/2 lb increments. Something like that will do just fine.

water is going thru the water line? What do you mean by thru? water may travel up the PRESSURE line a little but it shouldn't make it to the gauge head by any means. If it does, you got a bad gauge.

water IS traveling to gauge.

Thanks for all the replies everyone!

Check to make sure it's getting 12V when the ignition is on. If the needle won't jump it would be either no ignition or bad gauge.
