I prefer filling the entire chamber but not sure it's necessary!!


As I recall (I'm at Home Depot fetching the Vasaline) there are three, what could be called, chambers: One holds the drive gear and driven gear (impellers), one holds the pressure relief valve, and a third is a crescent about 2 1/2" long and less than 1/8" wide with a small hole either in it or just below it, what I am calling flow chambers.

Is all this packed? Or will it hurt to pack them regardless. I'm just afrid of clogging the non-moving channels with the vsaline.
