What is the normal fuel rail pressure for the Geely Borui?
3 Answers
Geely Borui's normal fuel rail pressure is between 300kpa and 350kpa. Other models: Depending on the model, gasoline pressure may vary. Generally, as long as it is around 300kpa, it is considered normal, which is approximately 0.3MPa. Measurement method: Turn on the ignition switch to operate the electric fuel pump. The fuel pressure at this time should meet the technical requirements, generally fluctuating around 0.3MPa. Clamp the return hose, and the reading on the fuel pressure gauge will be the maximum fuel supply pressure of the pump. This value should comply with the model's technical requirements, usually 2~3 times the working oil pressure, i.e., 0.5~0.75MPa.
When it comes to fuel rail pressure, it's a common question from Geely Borui owners in auto repair shops. The normal range is between 180 to 220 bar, depending on the engine year and temperature. From my experience, it's around 190 bar at idle and may spike during acceleration. A faulty fuel pump or clogged filter can cause low pressure, making the car hard to start and increasing fuel consumption; high pressure can easily burn out the injectors. During every maintenance, I recommend checking the fuel system and using a diagnostic tool to monitor the data stream—don't wait for the warning light to come on before fixing it. Addressing minor issues promptly can save big money and extend engine life. Remember to keep the fuel clean and avoid using low-quality gasoline.
I've been driving a Geely Borui for several years and have been quite diligent with its maintenance. Keeping the fuel rail pressure around 200 bar is quite stable, as the manual states the standard range is 180-220 bar. Last time when the pressure dropped, the car jerked during startup, and the issue was resolved after replacing the filter. Paying attention to this while driving can help reduce potential risks, especially since stalling or shaking in traffic can be very frustrating. You can simply monitor it by connecting to an OBD with a mobile app, but I recommend regular checks at authorized service centers. I usually get it checked every 10,000 kilometers to ensure safety and peace of mind, as performance directly affects fuel consumption and acceleration.
