FAQ

Q1: How do I confirm if this P43 delivery valve (134110-4420) fits my specific diesel pump?
A: First, locate the part number on your existing delivery valve. It should match either “P43” or “134110-4420” exactly. Second, measure the outer diameter and length of your current valve. Our standard size part (2x2x3 cm) is designed for common diesel pump applications. If your measurements match and the part number is identical, it is a direct fit.

Q2: What is the installation procedure for this delivery valve?
A: Installation is a precise mechanical process. We recommend having a certified diesel mechanic perform the replacement. The general steps include: 1) Depressurizing the fuel system. 2) Removing the old delivery valve holder. 3) Extracting the old valve and spring. 4) Cleaning the seating surface. 5) Installing the new delivery valve with a new gasket or O-ring (if applicable). 6) Torquing the holder to the manufacturer’s specification. Over-tightening can damage the valve.

Q3: What maintenance is required for this delivery valve to ensure long service life?
A: The delivery valve itself requires no direct maintenance. However, its lifespan is directly tied to the cleanliness of the fuel system. Regularly replace your fuel filters and use high-quality diesel fuel to prevent contamination. Contaminated fuel can cause scoring on the valve’s sealing surface, leading to fuel pressure loss and poor engine performance.
