Issues

Water Leak in Housing

Unscrewing the inlet hose, I discovered that the o-rings were kinda damaged. Replacements ordered.

O-Ring: 17mm OD 12mm ID 2.5mm Width

After receiving the o-rings from amazon, it appears that these are a little smaller than the factory installed ones. They do however appear to work well with no issues so far. The factory ones appear to be slightly thicker ~ 3.0mm.  With hat said you may want to try an o-ring: 18mm OD 12mm ID, 3.0mm Width.
