FAQ

Q1: How do I verify if this 294160-0200 valve fits my fuel pump?
A: Check the model number on your fuel pump’s data plate. This valve is specifically designed for DENSO HP3 and HP4 pumps. Cross-reference your pump assembly number (e.g., 294000-0039, 294000-0030) with the list provided in the OEM Cross-Reference section. If your pump number is listed, this valve will fit.

Q2: What are the symptoms of a failing pressure relief valve?
A: A faulty pressure limiting valve often causes difficulty starting, engine misfiring, black smoke, poor fuel economy, or a fuel pressure warning light. It can also lead to injector failure if the pressure is not properly regulated. Replacing this valve is a common repair for these symptoms on HP3/HP4 systems.

Q3: Can I install this valve myself, or do I need special tools?
A: Installation requires mechanical knowledge of fuel systems. While the valve is a direct screw-in replacement, the high-pressure system must be depressurized before removal. We recommend installation by a qualified diesel technician to avoid system contamination and ensure proper torque sealing.
