"I use this air operated pump to transfer motor oil from 55 gallon drums into my trailer. Every other pump I could find was at least twice the cost so I was a little skeptical. I have tranfered only three drums with it so far, but it has worked great and exceeded my admittedly low expectations. It is of course not as smooth or fast as the diaphram pump I use for waste transfer, but it is also 1/7th the cost and seems better matched to my 6hp compressor. It reminds me of the thumper from "Dune." I highly recommend ordering a hose, adapter and nozzle at the same time. I didn't and had to run around the farm store trying to find something. I ended up with a ten foot hose for fuel transfer as well as a simple fuel nozzle. They work great. A swivel would be a nice, but costly addition. You will need an air coupling and a drum wrench as well. Might as well get it all together and save yourself the running around I had to do."
