Zderf,
So that's what that valve's for, to charge the cylinder with 7psi! Live and learn. I too have the 160 psi gage and have yet to see the
oil pressure get much past 55 psi, as I'd expect
. I can read the gage easily though. Still, I will check into changing it in the future.
Glad to see that it is coming together for you!
All the best,
Randy Klein
