Parts for your 2010 Suzuki Splash-Fuel filter

2010 Suzuki Splash fuel filter: what’s fitted and what to service

Based on factory service information and parts catalogues, a 2010 Suzuki Splash may or may not have a serviceable fuel filter, depending on engine. Petrol variants (K10B/K12B) use a returnless, in-tank pump module with an integrated strainer/filter that isn’t a scheduled service item. Diesel variants (1.3 DDiS/Multijet, D13A) are fitted with a separate, serviceable fuel filter in the engine bay. This aligns with Suzuki workshop literature for K-series petrol engines, the Suzuki electronic parts catalogue (which shows the petrol filter built into the pump module and a standalone diesel canister), and common service databases used in AU/NZ workshops that list “no periodic replacement” for petrol Splash filters but specify replacement intervals for the diesel filter.

For owners of diesel DDiS Splash models, the fuel filter plays a big role in keeping the small, high-pressure common-rail system healthy. It traps fine particles and separates water that can damage injectors and the pump. Fresh, clean diesel and a good filter are your best mates for smooth starting, quiet running and decent fuel economy.

As part of regular servicing, most workshops recommend replacing the diesel fuel filter at the interval in the logbook or service schedule, commonly around 30,000–60,000 km or every 2 years, and sooner if the vehicle sees poor-fuel environments. Signs it’s time include hard starting, hesitation under load, surging, or a water-in-fuel warning. Stick with quality filters that meet OE spec, as incorrect micron ratings can cause dramas with rail pressure and injector wear.

Replacement on the DDiS is straightforward but benefits from a few tips:

• Pre-fill or prime the new filter as specified, use the hand primer (if fitted) or cycle the ignition to run the in-tank lift pump and purge air.
• Renew O-rings/seals, torque clamps correctly, and check for leaks with the engine idling.
• If the housing has a water drain, crack it periodically—especially after suspect fuel—to clear collected water.
• After any filter work, clear warning lights and confirm rail pressure and smooth idle on a short road test.

Driving a petrol Splash? There’s no separate, serviceable inline fuel filter. The in-tank strainer is designed for the life of the pump and is only addressed when the pump module is replaced. Good-quality petrol and timely maintenance of the ignition and intake systems go a long way to keeping things sweet. If there are fuel delivery concerns, a pressure test and scan for trims is the right first step rather than hunting for a non-existent external filter.

• Popular questions about 2010 Suzuki Splash fuel filters

Does a 2010 Suzuki Splash have a fuel filter?

Yes and no. Petrol models use an in-tank pump module with an internal strainer that isn’t a regular service item. Diesel DDiS models have a separate, replaceable fuel filter canister in the engine bay.

How often should the fuel filter be changed?

On diesel Splash models, follow the logbook—typically every 30,000–60,000 km or 2 years. Shorten the interval if you’ve had a bad-fuel incident. Petrol models don’t have a scheduled fuel filter change.

Where is the fuel filter located?

Diesel: in the engine bay, usually mounted on a bracket near the firewall with two fuel lines and an electrical connector. Petrol: inside the fuel tank as part of the pump module, not serviced separately.
