# Fuel pump

> The fuel pump is the electric pump in fuel-injected motorcycles that delivers fuel from the tank to the injector at constant pressure.

- **Also known as:** Yakıt pompası, Benzin otomatiği, Fuel pump

The pump usually sits inside the tank as a module with the fuel filter, pressure regulator and fuel level sender. It runs for a few seconds when the ignition is switched on to pressurise the system; the short whirr you hear is normal.

## Symptoms of a problem

- No pump sound at ignition-on and the engine will not start
- Loss of power or cutting out at high revs or uphill
- An incorrect fuel gauge reading (level sender)

Carburettor motorcycles and scooters usually use a vacuum-operated fuel tap or vacuum pump instead.
