I installed a cheap gauge on my on broad air system and the clear lens came off. I need a good gauge maybe have it inside the cab. Would a fluid filled gauge would be better. Plus any ideas of where to get one I live in a remote area that would help to. Right now my gauge is installed under the hood and is screwed into a tee fitting.

 

Fluid is used for dampening purposes, unless your gauge before was fluttering while in use, then a fluid filled gauge would have no advantage to you. Most air pressure gauges are not fluid filled.

 

Yea I knew that but I think the lens is better a setup that wouldn't come off. My gauge still works just has no lens so it must not have handle the off road use I gave it.

 

I would also have you consider that the accuracy of the liquid filled gauge will change dependant on temperature. Being its inder the hood, you'd find things to read incorrectly if it gets hot/cold. I would assume the lens to be better, but accuracy would be a concern.
