how to use the pump

Install the pump (It is very important.)

1.The pump should be installed vertically and  little lower than the lowest fuel level of the tank.

2.Fuel inlet and outlet ends should be set at the bottom oil line of the tank.

3.The input and output fuel tubes must be laid at the same level.

4.The oil filter weight block should be always in the bottom of tank and in the oil, avoid the air entering the tube when oiling.

5.Each time before starting, the oil tube and the pump must be full of oil without air. Don't start the pump suction directly for the first time, you must use external device (for example the hand pump) to fill oil in the pump, then you can use pump normally
