INSTALLATION SERVICE POINTS

.

>>A<< CAP INSTALLATION

CAUTION

Install the packing to the fuel tank, and then install the fuel 
pump module to the fuel tank. Installing the packing to the 
fuel pump module will damage the packing lip when 
installing the fuel pump module to the fuel tank, and fuel 
leakage will occur. 
1. Check that the fuel tank is not damaged or deformed, and 

then securely install the packing to the fuel tank.
NOTE: If the packing is damaged or deformed, replace with 
new packing.

CAUTION

• Do not tilt the fuel pump module when installing.
• The packing should not be folded over as shown by "A" 

in the illustration.

2. Apply soap water to the inside of the packing, and then 

install the fuel pump module.

CAUTION

When tightening, be careful not to let the fuel pump mod-
ule turn together with the cap. If the mating marks are mis-
aligned, the float may measure a remaining amount of fuel 
in correctly, causing the low fuel warning light to malfunc-
tion.
3. Use special tool MB991480 to align the mating marks on the 

fuel tank and fuel pump module, and tighten the cap.

.

>>B<< FUEL HIGH-PRESSURE HOSE INSTALLATION

CAUTION

Connect the high-pressure hose, and then pull it gently in 
the direction of removal to check that the hose is firmly 
connected.
Apply clean engine oil to the tips of the main pipe nozzle and 
the fuel main pipe, and connect quick-joint connector of the fuel 
high-pressure hose to them.
