High Pressure Fuel Pump Removal/Installation [L3 With Tc]; Fuel Leakage Inspection After High Pressure Fuel Pump Installation - Mazda CX-7 2007 Workshop Manual

Caution
• If the high pressure fuel pump installation bolts are tightened with the high pressure fuel pump
tilted, the high pressure fuel pump may not operate correctly. Tighten the high pressure fuel pump
installation bolts in a few passes with equal torque.
14. Tighten the bolts on the high pressure fuel pump.
Tightening torque
8.5— 11.5 N·m {87— 117 kgf·cm, 76— 101 in·lbf}
Warning
• If the high pressure fuel pump joint nut is loosened, fuel leakage may occur resulting in death or
serious injury, or damage to the equipment or the vehicle. Fuel can also irritate the skin and eyes.
When installing the high pressure line pipe, always tighten the high pressure line pipe installation
nut while fixing the high pressure fuel pump joint nut with a wrench. If the high pressure fuel pump
joint nut has rotated, replace the high pressure fuel pump with a new one.
15. Assemble the high pressure line pipe.

Fuel Leakage Inspection After High Pressure Fuel Pump Installation

1. Verify that the high pressure fuel pump is assembled securely.
2. Drive the vehicle starting from a standstill and brake suddenly five to six times at a low speed.
3. Stop the vehicle and verify from outside the vehicle that there is no fuel leakage around the high pressure fuel
pump.
