Been using the original Topsider for about 8 years now @ 3K oil change intervals.
I changed the hoses and added a ball valve to shut it on/off. Just pump it up 40-50 times, insert the hose, open the valve and let it do her thing. I pull the hose out alittle once in a while (to listen for that "slirping" noise) to check vacuum and then stick it all the way down again, sometimes pumping it up again. With the hose fully inserted, and that slirping noise constant, I know I'm done.......... In the meantime, I'm changing the oil filter, checking all the other fluids, getting the new oil containers open, etc, ready to finish the job. Takes about 1/2 hour....total.
