Where is the Honda City Fuel Pump Located?
2 Answers
Honda City fuel pump is installed in the fuse box in the engine compartment, while the fuel pump is mainly located inside the fuel tank, responsible for pumping fuel from the tank to the engine for combustion via fuel lines. Fuel pumps are categorized into gasoline pumps and oil pumps; the gasoline pump is installed in the fuel tank, whereas the oil pump is located inside the engine. Below is an overview of the main working principles of the gasoline pump: 1. Currently, most vehicle models have the fuel pump installed inside the fuel tank, powered electrically. The fuel pump consists of three main parts: the pump body, the permanent magnet motor, and the housing. 2. When the permanent magnet motor is energized, it drives the pump body to rotate, drawing fuel in from the inlet, passing it through the internal structure of the electric fuel pump, and then pressing it out from the outlet to supply the fuel system. 3. The fuel flowing through the electric fuel pump cools the armature of the permanent magnet motor, hence it is also known as a wet fuel pump. 4. The motor part of the electric fuel pump includes a permanent magnet fixed to the housing, an armature that generates electromagnetic torque, and a brush device installed on the housing. 5. The brushes contact the commutator on the armature, with their leads connected to terminals on the housing, directing the control voltage of the electric fuel pump to the armature windings. The housing of the electric fuel pump is crimped at both ends, assembling all components into a non-detachable unit.
The Honda City's fuel pump has a rather unique installation location—it's submerged inside the fuel tank. I've replaced this component before, and you have to lift up the rear seats to access it, right at the fuel tank opening beneath the seats. Having the fuel pump inside the tank offers several advantages: it's cooled by the gasoline, reducing the risk of overheating, and it ensures stable fuel supply pressure. However, replacing it yourself requires caution. You'll need to remove the seat clips first, and there's a risk of fire from gasoline vapors in the tank. It's advisable not to attempt this yourself, as the job involves fuel line sealing and electrical connections. Professional repair shops are safer, as they have fuel extraction equipment. Symptoms of a failing fuel pump are quite noticeable, such as jerking when accelerating and difficulty starting the engine—both are clear warning signs.
