How to Deal with Abnormal Noise from Haval Fuel Pump?
3 Answers
Gasoline filter is too dirty and has not been replaced for a long time. Long-term high-load conditions can easily damage the fuel pump, which needs to be replaced. Using poor-quality gasoline, which contains various impurities, foreign objects, and additives. Unfiltered impurities entering the fuel pump motor will accelerate wear. Fuel tank running low on fuel increases friction in the fuel pump, causing abnormal noise. Refuel the tank in time. Damage or deformation at the bottom of the fuel tank causes excessive resonance between the fuel pump and the tank bottom, resulting in a buzzing sound.
I've been working on car repairs for many years. There are usually several reasons for abnormal noises coming from the Haval fuel pump: the most common one is when the fuel tank level is too low, causing the pump to run dry and produce a humming sound. In this case, simply filling up the tank can alleviate the issue. Another possible cause is a clogged fuel filter or internal wear and aging of the pump, which can result in a rattling noise. To address this, first check that the fuel gauge doesn't show less than 1/4 tank, add some fuel, and take a short drive to test. If the noise persists, it's best to take the car to a professional shop as soon as possible to inspect the pump motor and wiring connections. Ignoring small issues for too long can lead to pump burnout, costing you thousands for a replacement. It's recommended to replace the fuel filter every six months and avoid driving with low fuel levels to develop good habits and prevent major repairs. Safety is crucial, as fuel pump failure can cause the engine to stall and lose control, especially posing significant dangers on highways.
I've been driving my Haval for almost five years and have also experienced fuel pump noise. One day when I started the car, it suddenly made an annoying buzzing sound. I asked an experienced driver about it, and he said it was probably due to low fuel or a clogged filter. I immediately went to the gas station and filled up with 98-octane fuel, but after driving for 15 minutes, the noise was still there. Later, I took it to a small auto repair shop in the parts market. The mechanic removed the pump and found some rust inside causing friction noise. After cleaning it, the problem was fixed. Now I've learned my lesson: during every maintenance, I make sure to replace the filter, and I refuel when the gauge drops to 1/3 to avoid damaging the pump by running it dry. It doesn't cost much, but you need to act early—don't wait until you're stranded on the road to panic. Safety comes first when driving, and strange noises are not a small matter.
