Ive got an autometer mechanical boost gauge that I think just took a crap on me. Guage isn't showing any boost and both ends of the hose are still connected. My truck still seems to be running the same as it has since the blower install. Anybody had an autometer mech. boost gauge go out?

 

Not sure if mine was autometer or not, but had same problem. Dealer installed a new one free for me (they could afford to given what I paid them for S/C and install!

D

 

I have to replace mine too. FOr whatever reason, with the engine off it reads about 3-4 in/mer (negative). Don't know why...

 

I had one break on me while it was parked over the winter. Went out one day and it was reading 5 psi. I sent it to Autometer, and they sent me a new one under warranty.
