Limiting Valve – Keeps the
pressure in the fuel return line
at 14.5 psi (100 kPa / 1 bar).
This maintains a force
equilibrium at the pump/
injector solenoid valve needle
Fuel Supply Line Pressure Limiting Valve –
Regulates the fuel pressure in the fuel supply line.
The valve opens when the fuel pressure exceeds
109 psi (750 kPa / 7.5 bar). Fuel is routed back to
the suction side of the fuel pump.
