To tighten up the sloppy fit between the two halves of the assembly, and to provide more clearance between the umbrella and the housing, I made a new housing from Delrin. The new housing has a stepped bore.
It overlaps the major diameter of the body (like 1.345") with a push fit. That holds the assembly together while still permitting disassembly for maintenance.
It has a minor bore in way of the new o-ring (like 1.170"). That stabilizes the assembly and gets rid of all the wiggling, and of course provides a nice sealing surface.
And for the remainder of the bore in way of the umbrella valve, its about .050" larger than the original (like 1.255"). That provides additional clearance between the housing and the circumference of the umbrella valve.
