What is the ampere rating of the Beidouxing fuel pump relay?
2 Answers
The Beidouxing fuel pump relay is rated at 15 amps, and the fuel pump relay serves as the control switch for the fuel pump. Taking the 2019 Beidouxing model as an example, it is a microcar with body dimensions of 3400mm in length, 1575mm in width, and 1670mm in height, a wheelbase of 2335mm, a fuel tank capacity of 42 liters, and a curb weight of 900kg. The 2019 Beidouxing features a MacPherson strut front suspension and a non-independent single trailing arm rear suspension. It is equipped with a 1.4L naturally aspirated engine, delivering a maximum horsepower of 97PS, a maximum power of 71kW, and a maximum torque of 120Nm, paired with a 5-speed manual transmission.
As a veteran driver with twenty years of experience driving the Beidou Star, I remember that the fuel pump relay is commonly rated at 15 amps, which is the original amperage used in the car. Using a relay that's too large or too small isn't advisable: 15A matches the fuel pump's power perfectly, ensuring stable current and a long relay lifespan. If you switch to a 20A relay, it might cause overheating or short circuits in the wiring. On the other hand, a 10A relay is prone to burning out, which could lead to a dangerous fuel pump failure while driving. The Beidou Star is a durable car, but its relays tend to age quickly, so I recommend checking them every 20,000 kilometers. If you encounter a fuel delivery issue, first test the original amperage. If you don't have the manual, just buy a universal 15A relay from an auto parts store. After replacing it, test the idle speed—if it's stable, you're good to go. Safety comes first when driving, so don't take any chances.
