Pressure Relief Valve and Sealing Washer
Replacement, Bosch P7100 (5-29)
The pressure relief valve arrangement on the Bosch P7100
injection pump in the supply side of the fuel circuit creates
a self-bleeding system for air introduced during replace-
ment of the supply side components.
A sticky or malfunctioning relief valve can result in engine
miss, low power or hard starting.
The Bosch P7100 injection pump has a jump-over tube to
route return fuel and entrapped air from the pressure
relief valve directly to the supply tank.
