Can You Still Drive with a Faulty High-Pressure Fuel Pump?

[LeAnnie]

You can still continue driving. Early symptoms of a faulty high-pressure fuel pump may include weak acceleration, jerking during sudden acceleration, difficulty starting, illuminated engine warning light, and unstable idle. When the high-pressure fuel pump fails, simply replace it with a new one. It is recommended to use genuine parts and have the replacement done at an authorized 4S shop. Below is an introduction to the high-pressure fuel pump: 1. Main materials used: The high-temperature and high-pressure all-carbon-steel gear-type residual oil pump primarily uses Q235 ordinary carbon steel for its three main components. Gears, thrust plates, and other parts are made of alloy structural steel and undergo special heat treatment to significantly enhance hardness and wear resistance. 2. Unique performance: The high-temperature and high-pressure all-carbon-steel gear-type residual oil pump employs proprietary hydraulic balancing technology, delivering high efficiency, low noise, stable pressure, and extended pressure-holding time under high-temperature and high-pressure conditions.
