Hi Larry,
The fluid is low because the sight glass is broken. The fluid MAY be at the very top, but the fluid low marking is about half way in the sight glass. Anything between low and high is just fine. The level of the fluid has no bearing on the pressure which is controlled by the air in the internal bladder. I have never seen air bubbles in the sight glass.
Thanks for the tip on your repair. Did you remove the "glass" and put some epoxy on the inside, or just apply epoxy from the outside? I am pretty set on having a new piece machined. It is an interesting piece, tapered over its length with different sealing diameters at each end. Howard sure made it complicated to reproduce. Iron Horse RV which did many of the installs say they just replace it with a piece of copper pipe. It certainly sounds as though the sight glass was a weak point in the design. Russ
