RE: GAS Fuel Can
Here is the actual Facet pump I use. I believe I bought it at PepBoys or one of the other large retail chains several years back.

Please note that automotive fuel pumps, such as the Facet, are one-way pumps. You cannot use them in reverse to empty your tank. I arranged my plumbing to my gas tank so that I can connect the pump's outlet to the airplane to fill, and I can connect the pumps inlet to the airplane to empty.
The upside is that they are DESIGNED for gasoline. They prime NOW, there's no waiting for them to start sucking fuel like a gear pump. They last pretty much forever, don't leak, and they don't go boom.
