I've had a few different regulators in my day and abused all the ones I've had on an OBA system. I've gotten a few cheap HF ones so hot the plastic window on the gage discolored but the gage and the regulator still worked. The most common problem I've found is the accuracy of the gage itself, even when new. I had 2 gages on my old truck and they were close to 10 psi off between the 2. Didn't really matter to me but nonetheless, they weren't the same.Originally Posted by Robinhood4x4
