Removing the fuel manifold / injectors
Remove the fuel manifold with the injectors mounted on it.
Attention! Be careful not to drop the injectors when removing the fuel manifold.
Installing Injectors/Fuel Pressure Regulator/High Pressure Fuel Hose
Apply some clean engine oil to the O-ring before installation.
Attention! Be careful not to let oil get into the fuel manifold.
While turning the injectors, high pressure fuel hose and fuel pressure regulator left and right, carefully install the fuel manifold so as not to damage the O-rings.
After installation, check that the flange of the high pressure hose in the fuel manifold turns smoothly.
If the fuel hose flange does not turn smoothly in the fuel rail, the O-ring may be pinched. In this case, disconnect the high pressure hose from the fuel manifold, reinsert it into the fuel manifold, and check that the hose flange rotates smoothly.
Tighten the high pressure fuel hose flange bolts to standard torque and the fuel pressure regulator bolts to the specified torque.
Tightening torque: 9 Nm (fuel pressure control).
