thanks for replying I knew I was off track with the shop vac idea but needed someone with better knowledge to tell me it wouldn't work. lol Wife says I'm too frugal to put it nicely so I'll invest in a 2 stage pump thanks again
Vacuum powered liquid extractor!
so would a shop vac work if the connections could be altered to fit? lol I don't have a vacuum pump but need to replace the transmission fluid in our 4-runner and it has a sealed transmission so no dip stick and really don't want to invest in the hvac pump. I guess a shop vac would be considered a 1 stage pump if my thinking is right lol maybe
I upgraded to get the plans for this project and talk about being disappointed. I was wanting the measurements for the lay out of the curves and there was nothing on it just use a BBQ lid. Don't upgrade to get these plans they are worthless and left me feeling ripped off
