Jim,
Here are photos of the sight gauge on the 320 and the IV. Basically done the same. On the 320 I covered the AN842 with micro and shaped it. On the IV I left it exposed. Actually, I like the exposed version better.

Jim,
A sight gauge is an excellent accompaniment to a header tank. There are, of course, many ways to fabricate the gauge. My choice is to use clear PVC tubing (Spruce p/n 03-54100). You tap the ends to accept AN842 90 degree fittings. Drill two holes in the panel to accept the hose end of the 842s. Insert rubber grommets in the holes. push the fittings through the grommets. Put a hose clamp over the hose on the back side of the panel which will secure the hose to the fitting as well as hold the sight gauge to the panel. On our IV we also put a 3 sided square channel around the tube for protection from accidental bumps.
