I was not interested in an elaborate system, but I did want a way to verify pressure without using a tire gauge. The system is tight and the only pressure loss was from checking it with the tire gauge.
We had a problem with our generator dieing if we ran it for a couple of hours while parked in 90 degree temperatures. We read where the pump fails prematurely due to overheating because of its location. Moved it out of the generator compartment and installed new pump and filter. Problem solved.
