Review on Kodiak Controls KC301L251000 DSM3511 Pressure by James Crofton

Warning, my pressure gauge was not correctly set to the diaphragm seal. They didn't pump out all the air, so the diaphragm touched the bottom, resulting in a useless gauge/seal assembly. I disassembled this factory assembly and installed the sensor CORRECTLY on the gasket and now it works perfectly. So if you're buying this assembly because you don't have the hardware to properly mount the gauge to the gauge gasket, I wouldn't buy this assembly. If you're buying this assembly so you don't have to waste time putting a pressure gauge on the gasket, I wouldn't do it. You can find a functional equivalent to this (but better quality) factory assembled (ownership) one for the same or very close $$, so I don't recommend it to anyone. Too bad the build isn't trustworthy as the indicator and seal are of decent quality, but having to reassemble it won't save you either time or money.
