Thank you, Gilly, you cleared up a lot of questions I had. I was assuming that the extractor "tool" was just the little adapter portion that connected to the dipstick tube and that this then was connected to a shop pump source, not realizing that the extractors you were refering to, were the actual shop grade aparatuses for creating the vacuum, holding the oil, transfering to the holding tank, etc.
I think I'm just interested in the adapter itself and seeing if the TopSider (which is basically a fuel can with a bicycle pump attached for creating the vacuum, connected to a small plastic hose that is feed down the dipstip tube) could use it. Will look into that Iowa distributor.
Thanks very much!!
