Rebuilt the 48 IDA and it's looking better.
Picked up a McDaniel Control 1.5" 1/8"npt 0-15psi gauge.
Even though it isn't glycerin filled, I figured this would be better than a cheap-o Chinese one.
I've got a 2" McDaniel all steal gauge with glass face 0-10psi but it's too bulky to keep attached to the lines. It sticks out way too much with the snubber and 1/8" adapter.
