Works as it should. Couldn't be more happy with it....recently purchased and installed as a water source for an asphalt sealer trailer. Love this pump.

Used to pump oil and works well

Pump is kind of a cheap unit. Paint not the greatest and instructions are in broken English at best. Saving grace is this thing will pump some oil! I used 1" lines with a 3/8" air line. Best to secure the outlet hose because it is like a fire hose! I am only pumping waste oil and gear fluid, have moved about 1,000 gallons and it has not slowed down yet!
