April is the month for doing the annual service on the generator/alternator. Draining the oil on the unit however has been a PITA because the drain is attached to a hose that barely makes it out of the cabinet. Worse, that makes the end of the hose higher than the bottom of the oil pan and thus, doens't get all the oil.

I had a Generac tech here last week to update the firmware and clear a pesky error that I couldn't. I mentioned the problem with the oil and he suggested picking up one of these little pumps that attaches to a cordless drill.

So, I went seaching and found what I think is an even better solution. To wit, a 12v oil drain scavenge pump, which is depicted in the photo.
