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

I used this to drain the transmission oil before changing the filter and it took just over an hour to pump out 2.25 litres, I expect there is plenty more left in the sump. I'm not sure if the pump stopped working or if the machine ran out of pumping oil. It has ridiculously short power cords that look extremely flimsy. And the pump hoses are ridiculously short, too. And please someone post the correct diagram of all the tubes and where they all go. Mine came with all the clear tubes separate…

I have an Audi A4 and the under covers are very difficult to remove when changing the oil. I figured for the money I'd try this little pump and it would work. The hose on the intake side flattened out a bit during the process due to the thickness of the oil, even though it was warm 0-W20 synthetic oil. The Revain picture shows a reinforced hose where the inlet connects to the pump, but I didn't have one. It took about 7 minutes but all the oil was pumped out and I saved 1 oil change on what I…

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…

Pump works well. Deducted a star for less than star alligator wires which are short and 18 ga wire. even used. The replacement cables fit perfectly. Simply remove the two Phillips head screws and the pump separates from the motor. You will need (2) solderless quick disconnect terminals. The positive wire must be an insulated plug. The size of the protrusion is not 0.25, but the next smaller size (0.210?). This pump is ideal for heavier and longer cables. The hoses supplied for the suction side…

Product exactly as advertised, works great drained 6.5 liters of oil from my diesel in less than 2 minutes. There are no additional instructions other than those in the product description, but its use is very simple and clear. The pump came with pre-filled plugs on both the inlet and outlet. If you don't remove the plugs, you're likely to get poor suction. If you leave the pump running without any liquid being pumped, or if the flow is going in the wrong direction, you will likely shut off the
