I came across some tech notes from manufacturer regarding failures, what to look for, what to avoid, and when to service that I found informative. Maybe others will benefit too

Thanks 240D Bill. Great information.

Too bad there aren't any repair parts available. I didn't even know that the ramp could be changed. It may be good to snag both the pump and ramp when at the yard.
