My Autometer Phantom boost gauge has become lazy. It doesn't want to return to neutral when the truck is turned off, stays at 10psi vaccum.

Can I recalibrate the gauge, or does it have to be sent back to the manufacturer?

 

I had one that only read 10lbs at wide open.
I called the manufactuer and ended up throwing it away and bought a new one from Ford Racing.

 

Take the guage out of the pod and pull the light socket out of the back. Look inside the light socket hole. There is a semi-flat looking large copper tube that winds about 2/3rds the way around the inside of the guage body. One end of the tube is connected to a boost source and the other end is connected to a gear arangement.

Anyway.....get in there with a pencil or something and push on that tube and watch the guage face you will see the dial move.
Now with a little bit of messing around you should be able to calibrate your own boost guage. Keep pressing on the tube until the gauge reads "0". AND DONT BREAK ANYTHING

PS this is common with the autometer boost guages that I have used....they almost never read "0" out of the box and further more when the weather changes so will your "0".

 

Thanks SLVR', I'll give it a try tomorrow.

I took a shop air line and blew air into the gauge making it sweep to max and then it came back to zero. Gauge works fine now.
I tried the other way with calibrating it myself and could not get it right.

Thanks Bruce, I'll give your fix a shot before I pull the gauge.

No problem. I'm on my second Autometer gauge and decided to try that and now I have an extra gauge laying around. lol

OK, I tried the compressed air method. Didn't work, at least not on my gauge. But, a great idea.

Pulled the gauge and messed with the flat copper tube, and got the needle back to "0". Hooked up a MityVac and pulled vaccum several times and still returned to "0". Guess I'll see tomorrow when I drive the truck, if it is truely fixed.

Thanks for the help guys.
