Fuel Pressure Regulator: Service and Repair
NOTES:
-
Whenever the fuel injection pump is being replaced or removed for calibration, the overflow valve must stay with the pump. Make sure a new
overflow valve is used with a new injection pump and the old (original) overflow valve is returned to the authorized repair facility with the old
injection pump.
-
The overflow valve (pressure relief valve) is located at the inside/front of injection pump. It connects the fuel return line (banjo fitting) to the
pump. The valve has no internal serviceable parts and must be replaced as an assembly. Two sealing gaskets are used. One gasket is located
between pump and banjo fitting. The other is located between the banjo fitting and end of valve.
REMOVAL
1. Clean area around overflow valve and fuel return line at injection pump before removal.
2. Remove valve assembly from pump and banjo fitting. Do not remove retainer from valve. This retainer is spring-loaded. If fuel return line must be
positioned for removal, very carefully bend line.
3. Discard old sealing gaskets.
INSTALLATION
1. Install new sealing gaskets to valve.
2. Install valve through banjo fitting and into pump.
3. Tighten to 30 N.m (24 ft. lbs.) torque.
