INSTRUCTIONS

Installation steps for the High Pressure Fuel Pump

1. Detect the high pressure pump O-ring, and use clean engine oil to slightly wet the insert roller tappet into the vacuum pump. Pay attention to align the recess of the roller tappet with the groove on the vacuum pump.
2. Rotate the crankshaft until the roller tappet is at its lowest point. Insert the high pressure pump into the vacuum pump.
3. Cross tighten the fastening bolt by hand, and cross tighten the fastening bolt with the specified torque of 20 N·m. Insert the fuel hose again and fix it with spring clamps. Connect the fuel pressure regulator.
4. Use engine oil to infiltrate the ball head of the high pressure hose and install the high pressure hose. Tighten the lock nut of the fuel distributor indicated by the arrow in the drawing with a wrench.
5. Fasten the high pressure pipe connector with a wrench and tighten the live joint nut of the high pressure tube with another wrench.
6. Install high pressure pipe clamps and use 5 N·m torque to tighten clamps (You can skip this step for models without high-pressure pipe clips).
7. Start the engine after installation to observe whether there is oil leakage on each interface.
