Product Description
OEM Common Rail Fuel Pressure Limiter 095420-0190
Denso Pressure Relief Valve with 1-Year Warranty for ISUZU NPR NQR NRR FVR FVZ 4HK1 6HK1 6WF1 6WG1
Product Overview
The Common Rail Fuel Pressure Limiter (Pressure Relief Valve) with OEM numbers 095420-0190 (also listed as 0954200190, 8-97318691-0, 8973186910) is a verified OEM-grade direct replacement for a wide range of ISUZU diesel engines. Manufactured by Denso to stringent OEM specifications, this pressure limiter is a critical safety component of the common rail fuel system.
- OEM Specification – Verified by Denso OEM part number 095420-0190 and cross-references
- Precision Engineered – Weight verified at 126g per unit, manufactured with CE and IATF 16949 certification
- Proven Durability – Manufactured under strict quality control standards with a 1-year warranty
- Broad Compatibility – Fits ISUZU NPR, NQR, NRR, NPR-HD, FVR, FVZ, 700P, ELF, Giga trucks and Hitachi excavators
- Critical Safety Component – Protects the fuel injection system from over-pressure damage
Failure Symptoms
If your fuel pressure limiter is failing, you may experience one or more of the following symptoms:
- Hard Starting / No-Start – The pressure limiter leaks internally and prevents the rail from building sufficient pressure
- Engine Stalling or Hesitation Under Load – Irregular fuel pressure regulation causes performance issues
- Excessive Exhaust Smoke – Black or white smoke due to incorrect rail pressure
- Reduced Power or Fuel Efficiency – ECU cannot maintain optimal rail pressure
- Fuel Leakage or Pressure Fluctuations – Visible fuel seepage or erratic pressure readings
- Diagnostic Trouble Codes (DTCs) – Codes such as P0087 (Rail Pressure Too Low) or P0088 (Rail Pressure Too High)
⚠️ Important: A failing pressure limiter can lead to progressive power loss, engine stalling, and costly damage to the high-pressure fuel pump and injectors. Prompt replacement is essential.
