I got a UMA manifold pressure gauge to replace my Vans faulty gauge. It has two ports on the back labeled V and P. The instructions say to hook V to the primer port on one of the cylinders. But it says nothing about P. What to do with port P is my question?

Thanks,

Tee it into the static source lines.

Port P has no threads...

In looking at it closer, the port labeled P has no threads. The port labeled V has NPT 1/8". So I'm guessing, there is no connection needed for P.
