Certificates and factories
8-98032549-0 The high-pressure oil pump pressure limiting valve (fuel) is an important part of the ISUZU 4JJ1, 700P and 4HK1 models. It precisely controls the fuel pressure in the high-pressure fuel pump to prevent excessive pressure from damaging the pump and related parts. Stable pressure ensures uniformity and accuracy of fuel injection, resulting in better combustion and improved engine power output and fuel economy. At the same time, it effectively reduces fuel system failures, prolongs engine life, and ensures that the vehicle is always in good operating condition.
