What are the symptoms of insufficient fuel supply from the fuel pump?

[EmmettRose]

Symptoms of insufficient fuel pump pressure include lack of driving power, insufficient acceleration power, stalling, and other similar issues. Below is more information about the fuel pump: 1. Introduction: The car fuel pump has four wires. Two of them are for the fuel level sensor (commonly known as the float), one is for power supply, and one goes to the fuel gauge. The other two wires are for the fuel pump itself, with one for power supply and the other as the ground wire. 2. Function: The fuel pump's role is to draw gasoline from the fuel tank and pressurize it through the pipeline and fuel filter into the carburetor's float chamber. It is because of the fuel pump that the fuel tank can be placed at the rear of the car, far from the engine, and positioned lower than the engine.
