The failure in fuel pump This is a common problem in all flex-fuel vehicles in Brazil, and Citroën models are no exception. The fuel pump is an electric motor submerged in the tank, and it burns out mainly due to two factors: the use of poor quality or adulterated fuel and the habit of constantly driving on reserve.
The main function of the fuel around the pump is not only to be pumped, but also to serve as… coolant and lubricant for the electric motor of the pump. When the driver drives with the tank on reserve (below 1/4), the pump is exposed to air and overheats quickly, leading to premature burnout.
Symptoms of a failing fuel pump include difficulty or delay in starting, engine hesitation during acceleration, and in extreme cases, the engine may stop working completely. The most important thing to check is… Never let the fuel level get too low. to ensure that the pump is always submerged and cooled.
