So i bought the gauge with the gauge kit and am getting ready to hook it up, Do i need to use the pressure gauge isolator shown in the pics? and if so what does it do? also i have a schrader valve coming off of my vp44 can i plumb the gauge in there?

 

Yes you need the isolator, it prevents fluctuations caused by the vp. And yes it can go where the schrader is, once it's been removed.

 

A needle valve will prevent water hammer. The isolator will keep you from having to run fuel into the cab. The isolator will have fuel on one side and antifreeze on the cab side. I don't mine having fuel in the cab, but some people don't like it. Hook your fuel line to the shrader valve on the vp then to a needle valve then to the isolator or the gauge.

Mu guess is that it didn't come with one. Go to Napa, they have them.
