Parts for your 2008 Ford Falcon-Fuel pump

2008 Ford Falcon fuel pump — what it does and when to sort it

On a 2008 Ford Falcon, a fuel pump is relevant and fitted to all petrol-injected variants (BF MkII and early FG). Ford’s workshop literature for BF/FG Falcons (Fuel System) specifies an in-tank electric fuel pump module on these models, and the owner’s/service data includes fuses/relays dedicated to the pump, underscoring its presence. The exception is the dedicated LPG “E‑Gas” Falcon of the same era: Ford’s E‑Gas service information describes a vapour LPG system with no petrol tank or petrol pump, and no in-tank LPG pump until the later EcoLPi system (introduced years after 2008). So, unless it’s an E‑Gas, the 2008 Falcon uses an electric in-tank pump.

For petrol 2008 Falcons, the fuel pump’s job is to deliver a steady, high-pressure supply of fuel to the injectors so the engine runs cleanly at idle and under load. Sitting inside the tank, the pump module typically combines the electric pump, a strainer (filter sock), level sender, and a swirl pot to prevent fuel starvation in hard corners. The engine control module commands the pump via a relay, priming on key-on and adjusting duty during driving so rail pressure stays on-spec.

Because the pump is cooled and lubricated by fuel, driving regularly with a near-empty tank isn’t ideal. Keeping at least a quarter-tank helps pump longevity. Poor performance, long cranking, hesitation under load, misfires at highway speeds, or a high-pitched whine from the tank are classic clues the pump or its strainer is on the way out. A proper fuel pressure test against the factory spec is the right first step before condemning the pump.

Replacement on these Falcons is usually a full module swap. It’s wise to fit a new tank seal and locking ring, and to replace the strainer. On BF MkII cars, there’s also an external inline fuel filter worth renewing at service intervals
