What are the symptoms of slight fuel pump pressure leakage?
2 Answers
Fuel pump slight pressure leakage may cause unstable idle, reduced power, difficulty in starting, and easy stalling. The fuel pump is responsible for pressurizing the fuel in the tank and delivering gasoline to the injectors through the fuel lines and filter, which is why the fuel tank can be placed at the rear of the vehicle. Relevant information about gasoline is as follows: Introduction: Gasoline is a volatile, flammable hydrocarbon mixture liquid distilled and cracked from petroleum, used as fuel. It appears as a transparent liquid, is flammable, and has a distillation range of 30°C to 220°C. Key characteristics: The important properties of gasoline include volatility, stability, anti-knock quality, corrosiveness, and cleanliness.
Last week, my car had a minor issue - it was particularly difficult to start, especially when trying to restart after parking in hot weather, often requiring multiple attempts. When accelerating, it felt sluggish, with the RPM rising slowly despite pressing the gas pedal, as if something was holding it back. The idle was also unstable, sometimes stalling for no reason at red lights. After inspection, the mechanic suggested it might be due to slight pressure leakage in the fuel pump, leading to insufficient fuel pressure and poor fuel delivery. Ignoring this could reduce fuel efficiency, wasting more gasoline and money, and even pose safety risks from potential fuel leaks. The recommendation was to regularly conduct fuel pressure tests and replace aging components to prevent bigger issues. Personally, I believe it's best not to overlook these minor symptoms to avoid costly major repairs later.
