Tank level probes

[Don Bradner]

I didn't see any response from this, posted May 9th. Today I flushed the waste
tank very thoroughly and removed a couple of the level-sensing screws.

What I found was that they are inserted into a specialized rubber grommet, which
has a captive nut on the inside, and when you tighten it swells up to seal the
connection. The two I removed were in bad shape, typical for 17-year-old rubber
exposed to wastewater, I suspect.

Earl says he has them in stock at $1.08 apiece, so I ordered 16 to do both black
and grey tanks.
