This is probably a dumb question but here goes anyways. My small pancake compressor has a rear mounted(1/8") 1-1/2" diameter pressure gauge. I'm finding it more difficult these days distinguishing the pressure reading on that small of a gauge. I'm considering putting a 2", 2-1/2" or even a 3" diameter replacement gauge in place of the 1-1/2" diameter. Is this a feasible alternative or is there a reason why the smallish diameter gauge was used in the first place, other than a cost savings for the mfg? One reason for asking this question in the first place was that I couldn't find any 1/8" rear mount pressure gauges larger than 1-1/2" diameter which made me think that maybe there's a reason why?
