Ya but if we didn't want to work on them we would all drive a new truck.

I thought I had a bad pressure switch at one time, I believe it was a bad ground. I bought a better brand pressure switch anyway then realized my ground was a bit shaky.
It is almost impossible to get leak free. Bad grounds cause a lot of people a lot of headaches.

They do look cheap. I put in SMC check valves and reused the leader hoses. So far so good.
