Method of mixing water into fuel tank

When refueling, because the fuel tank contains water, so that water mixed into the fuel tank, resulting in diesel hammer work abnormally.

Methods of elimination:

Remove the fuel pipe on the fuel pump, drain water until the flow is completely diesel oil, and then give the fuel pump exhaust. Remove the cylinder locking screw, place the fuel pump in zero gear, lift the landing gear and the upper piston, punch several times, remove the water in the cylinder, and then install the locking screw.
