Electric Liquid Transfer Siphon Pump - Mounteen Reviews
I have tested this pump and honestly I didn't expect it to work as well as it does. It is a very good and fast pump.
Works as described. Was a little wary of potential quality issues, but the quality is great, not flimsy at all.
Bought one for my cross-country trip this March. It saved me a few times when I was close to running out of gas - very convenient to just pump gas right out of a canister.
