Well boys, lo and behold I went to use my Liqivac and found that it had deformed on the last "hot" oil change. Now it would not hold a vacuum even with hose clamps in all the right places.
So, thanks to Scott's fine use of paintshop, I had a decision to make between the spiderman's extractor and the fine looking black number from Boats US. Well, it wasn't quite a toss up and they were kind enough to give me the July online offer price and free shipping to boot!
I'm expecting my new waterwolf bi-directional oil extractor/pump any day now.
No more pumping up for me!
