[AT] Oil Vacuum- Common sense solution?

[Mogrits]

This is tractor related: Does anyone have a clever way to suck oil out of a
sump or other confined space where you cannot get to the drain plug?

I saw a "Liquivac" device on the internet for 60.00, but I already have a
small "Mighty-Vac" system used for bleeding brakes and was wondering if I
could make that work.

Anyone done this or something similar to evacuate oil? Possibly even using
a shop-vac?
