I have the viair 480 dual pack which says it comes with a 165-200 pressure switch. But when my comps shut off my tank gauge only reads 175. Could it be the gauge or my pressure switch.

Thanks
Paul

Did you overtighten the fitting on the back? I did once and it turned the needle as well, so when I had a 175 pressure switch it was reading like 190, so it was off, change the gauge, and it read normal. Maybe its defective.

I had the same issue with the 480 combo back, and we had to order another pressure switch.
