Fuel Pump Replacement
Good gas atomization ensures maximum power. To ensure good atomization of the gas, it is injected into the engine under high pressure. The fuel pump creates and delivers pressurized gas to the fuel injectors.
The fuel pump is located either in the fuel tank itself or under the vehicle near the fuel tank. If the fuel pump is in the fuel tank, there may be a removable cover under the rear seats or trunk floor that allows access to the fuel pump. On many vehicles, if the fuel pump is in the fuel tank, the tank must be removed from the vehicle to replace the pump.

When considering fuel pump/fuel supply issues, remember that both fuel pressure and volume must be correct.
