How to Disassemble and Assemble a Single-Cylinder Diesel Engine Oil Pump?

[WalkerLee]

First, gather all the necessary tools for disassembly, then engage the parking brake and turn off the ignition switch. Remove the rear seat cushion. Clean the interior of the vehicle, and carefully remove the rear inspection hole cover using tools, taking care to proceed slowly as there are wires connected underneath. Disconnect the electrical plug from the negative terminal, remember the original installation position, then wrap the oil pipe with plastic film to maintain cleanliness. Use a screwdriver to first remove the retaining claws, then detach the No. 1 oil pipe, disconnect the filter hose, take out the fuel pump, disconnect the wires, and finally remove the fuel pump.
