FAQ

Q1: What is the function of this overflow pressure limiting valve?
A1: This component acts as a safety and regulation device for the HP0 fuel injection pump. It limits the maximum pressure in the fuel return line and allows excess fuel to bypass back to the tank, preventing over-pressurization and damage to the pump seals and injectors.

Q2: How do I know if this valve fits my 094000 series pump?
A2: Please check the model number stamped on your injection pump. This valve is designed for pumps with model numbers 094000-0300, 094000-0383, 094000-0450, 094000-0460, and 094000-0600. You should also verify your existing part number (should be 090310-0490 or 090310-0500) before purchasing.

Q3: What is the recommended installation procedure?
A3: Installation is straightforward. First, ensure the pump area is clean. Remove the old valve/screw. Apply a small amount of clean diesel fuel to the new O-ring (if applicable) or the threads. Tighten the new valve to the manufacturer’s specified torque. Do not over-tighten, as this can damage the housing. After installation, start the engine and check for leaks.
