Fuel Pump Controller – Kia (33040-J5000)

Fuel Pump Controller delivers fuel from the tank to the rail at the pressure the calibration expects. Output falls off gradually with wear, so the first symptom is usually a lean code or a misfire under load rather than a no-start.

Replace the Fuel Pump Controller when a lean code appears under load, when the engine cranks without starting, or when rail pressure bleeds down overnight. Change the fuel filter with the pump, because the debris that killed one shortens the life of the other.

For this Fuel Pump Controller the reference is 33040-J5000, in our Fuel Pumps & Senders range. Compare it with the number on the part you are replacing rather than with a photograph.

The stock here is genuine KIA, and this Fuel Pump Controller keeps the original engineering number, which matters once a number has been superseded more than once.
