Depends on the 6.5
Stewart Warner 114214
I think I'm going to go with this gauge. Judging how my operating pressure seems to be 4, and the 2 is so clearly a landmark. I should know I need filter service if I see it coming close to or hitting the 2.

LOL, a few months ago when I started this thread I was looking at the high end of the 15psi gauges instead of the bottom end
Ordered it off of E-Bay for 79.99.
