The reasons for the buzzing sound of the Nissan Patrol fuel pump are: 1. Internal wear of the fuel pump; 2. Faulty fuel filter. Taking the 2018 Nissan Patrol as an example, it belongs to the large SUV category, with body dimensions of: length 5165mm, width 1995mm, height 1955mm, wheelbase of 3075mm, fuel tank capacity of 100l, and curb weight of 2537kg. The 2018 Nissan Patrol features a double-wishbone independent front suspension and a double-wishbone independent rear suspension. It is equipped with a 4.0L naturally aspirated engine, delivering a maximum horsepower of 279ps, maximum power of 205kw, maximum torque of 394nm, and is paired with a 7-speed automatic transmission.
I've found several common reasons for the humming sound from the Patrol's fuel pump. As an owner of the same model, this noise often occurs when the fuel level is low - the pump sucks in air and produces a humming sound; if the tank is nearly empty, the vibration becomes more pronounced. Additionally, worn internal components like bearings or debris stuck in the pump can also cause abnormal noises. A clogged fuel filter increases pressure, forcing the pump to work harder and naturally making more noise. I once encountered this issue due to loose wiring connections causing voltage fluctuations, resulting in frequent humming. If not addressed promptly, it may affect fuel supply - sudden engine stalls while driving can be troublesome. I recommend regularly filling up the tank for test drives. If the sound persists, visit a professional workshop to inspect the pump and filter. Replacing faulty parts typically costs a few hundred yuan - don't delay until the problem escalates.
