Parts for your 2009 Suzuki Splash-Fuel pump

2009 Suzuki Splash fuel pump — what it does, where it is, and when to service it

Based on factory and aftermarket technical references, a fuel pump is absolutely relevant and fitted to the 2009 Suzuki Splash. Petrol versions (K10B/K12B) use an in-tank electric fuel pump module, while the 1.3 DDiS diesel uses a high‑pressure mechanical pump on the engine and, depending on market spec, may also have an electric in‑tank lift pump. Sources consulted include: Suzuki Global Service Information (Fuel System section), Suzuki Electronic Parts Catalogue (Fuel Tank/Fuel Pipe diagrams), Opel/Vauxhall Agila B technical data (platform twin), and Bosch common‑rail system listings for the 1.3 DDiS/Multijet.

On the Splash, the fuel pump’s job is to supply the engine with the right amount of fuel at the right pressure. In the petrol models, the in‑tank electric module feeds the rail so the injectors can meter precisely. In the diesel, the engine‑driven high‑pressure pump pressurises the common rail to very high levels for clean, torquey performance.

Owners typically notice a tired pump through hard starts, surging on hills, flat spots, a loud whine from the tank, or fault codes like low fuel pressure. Before blaming the pump, check the basics: stale or contaminated fuel, a clogged filter (especially on diesel), poor earths, and a weak battery can mimic pump faults.

For servicing on petrol Splash models, the pump module is accessed from under the rear seat through an access cover. Best practice includes:

• Depressurise the system and disconnect the battery.
• Work in a well‑ventilated area and keep sparks and heat away.
• Clean around the lock ring, replace the tank seal, and avoid dropping dirt into the tank.
• Fit a new strainer/sock with the module, then key‑on a few times to prime before starting.

The petrol pump strainer is generally non‑serviceable outside of pump replacement, so preventive care matters: keep at least a quarter‑tank of fuel to help cool the pump, and avoid contaminated fuel. On diesel Splash models, replace the external fuel filter at the recommended interval (often 20–40,000 km, check the service schedule) before condemning the high‑pressure pump. If the HP pump does need work, it’s a precision job—cleanliness and correct timing/bleeding are critical, and many workshops will scan for rail pressure, run calibrations, and verify leak‑off rates before and after.

A quality replacement pump (or module) that matches the VIN spec, fresh seals, and proper priming will keep a Splash running sweet, starting easily on cold mornings, and sipping fuel the way it should around Aussie and Kiwi city streets.

Popular questions

Where is the fuel pump on a 2009 Suzuki Splash?
On petrol models it’s an electric module inside the fuel tank, accessed under the rear seat via an access panel. On the 1.3 DDiS diesel, the high‑pressure pump is mounted on the engine, some market variants also have an in‑tank lift pump.

What are common signs the Splash fuel pump is failing?
Hard starting, hesitation under load, loss of power on hills, a loud whine from the tank (petrol), or fault codes for low rail pressure. Rule out a clogged filter (diesel), weak battery and dirty connectors before replacing the pump.

Is the fuel filter serviceable on the Splash?
Petrol models usually have a non‑serviceable in‑tank strainer that’s replaced with the pump module. Diesel models have a serviceable external fuel filter—changing it on schedule often restores pressure and protects the high‑pressure pump.
