FAQ

Q1: How do I verify if the A28 delivery valve (131110-4720) is the correct part for my engine?
A: The primary method is to compare the OEM number stamped on your old valve with our part number (131110-4720 or 1311104720). This valve is a standard replacement for many car engine fuel injection systems using the A28 model. If your old part number matches, it will be a direct fit.

Q2: What is the typical installation procedure for this oil outlet valve?
A: Installation should be performed by a qualified diesel mechanic. Generally, it involves removing the fuel line and the old delivery valve holder, extracting the old valve and spring, cleaning the bore, and installing the new valve assembly. It is critical to tighten the valve holder to the manufacturer’s specified torque to prevent fuel leaks and ensure proper injection pressure.

Q3: How can I ensure the longevity of this delivery valve after installation?
A: Longevity depends on fuel quality and system maintenance. Always use clean, high-quality diesel fuel and replace your fuel filters according to the vehicle manufacturer’s schedule. Contaminated fuel is the primary cause of premature wear on precision injection components like this delivery valve.
