Super suckers for the win!! Mine is pretty much just like FiremedicEric's just used different materials.

120 gallon Propane tank, 50 foot of PVC clear flexible hose, top hose with stand pipe for getting oil out, and 12 volt vacuum pump now mounted to the tank with a plug in the back of my truck on a switch. The same pump with switching hose pressurizes the tank in minutes and pushes oil out of the standpipe into the hose. 55 gallons in or out in minutes.

Now sure how well it will work in Michigan winters but if this won't suck it up neither will a pump. I have about $200 invested in this. 75% of that is the hose and cam locks.

I got the pump off ebay for $35. Murphy sells them for over $100. Tank was traded for scrap metal I was bringing into the scrap yard. Now I just need more barrels that are full to suck up!
