How to Install a Prewssure Guage

There are two or three ways to Install a Pressure guage on your machine. Never Install it on the HOT water side though. It will mess up the guage. Here is a picture of how I reccomend you do this.

Thanks Wiz,

Just saw this. I have to install one this week. I'm putting on a new unloader and have to test the pressure.

when you adjust the unloader it should spike only about 400 psi above the set pressure if it is a lock up unloader. if you want to do the time test it should unload within about one second any longer is set too high.
