[rigi1]

Guess I'm not alone. my switch blew in the driveway
sunday and dumped 4 quarts on driveway. Found an
original replacement today from cummins/onan for only
8 dollars. Easy fix.

What a mess that must have been. My leak started in my
brother-in-law's driveway in Overland Park, KS. Just a few
drops on his otherwise clean drive. The it really went near
I-94 in Kalamzoo, Michigan. I tried to clean up the mess the
best I could with paper towels, but then I only lost a pint or so.
Not the entire sump like you did.

The Onan cashier must have mis-read the invoice and collected
*just the sales tax* that was due on your purchase.

A gol-dang'ed old can of Coke in their waiting room is at least $15!
