If your in doubt about buying this pump as I was. Let me put your mind to rest. It will pump water with more pressure than a hose pipe.... thinking of using it for diesel and oil? Yep it does that too and under pressure. Changed the diff and gearbox oil in my jeep using the pump. Pumped 75w90 gear oil though 1/2” pipe no problems.... fantastic all rounder.... only tip I can give is flush out the pump with some water after use so the oil/diesel doesn’t start to break down the pump and you should be fine.
