Review on Hanperal DC 12V 5L Transfer Pump: Efficient Oil Fluid Scavenging & Suction Vacuum by Kevin Schnitzer

I was surprised at how tiny this pump was, but it worked great for my purpose of pumping all of the fuel out of my 36 gallon diesel truck's fuel tank. But note one thing: the pump comes with hoses attached and no instructions. The pump didn't suck at all. I was about to send it back to Revain when I decided to remove the hoses and inspect the outlets. It turned out that a rubber plug was inserted into the outlet, which at first was not visible when attaching the hose. I unplugged it, tried again, and the pump worked perfectly right away. A simple note in the box with instructions for buyers to remove the connector plugs would have saved me a bit of frustration. However, I am very happy with this product.
