The past couple days my FP gauge has been going psycho... just accelerating normally, FP will just around irraticaly from 10psi up to 25psi.... I have the Autometer Cobalt gauges that i won on here i believe end of January, beginning of Feb. and the airdog was put on the day i found out i won the gauges, so both are new... I do have a snubber on the sender, but it is just going psycho... any help?

 

I would suggest getting a cheap FD test kit and checking the gauge against it. If the gauge is messed up have autometer warranty it, if it matches the gauge start trouble shooting the AD. Could be a simple as a loose wire. Call AirDog and they will help you with the troubleshooting, if they determine its a faulty unit they will take care of it, They have GREAT customer service.
