I'm pretty sure this is hopeless but thought it couldn't hurt to ask. Otherwise seems like a nice gauge.
I have an almost new Monkey Grip tire pressure gauge. Circular gauge with a needle indicator. Problem is needle points to center readings of gauge instead of the 0 point. I tried the two screws in back, no help. I tried unscrewing tire connection. No help. I'd like to fix this - hate to throw away an almost new gauge. Can't seem to get glass face off to get at needle.
Anyone have any ideas? I tried Google - no help.
