Parts for your 2017 Suzuki Splash-Fuel filter

2017 Suzuki Splash fuel filter: what’s actually fitted

According to Suzuki factory service information for the Splash with K10B/K12B petrol engines and the published maintenance schedules for late-production models, there’s no separate, serviceable in-line fuel filter on a 2017 Suzuki Splash. The filter media is integrated into the in-tank fuel pump module (often called a strainer) and isn’t listed as a periodic replacement item. This design mirrors other Suzuki small cars of the era and is standard practice on modern returnless EFI systems.

That integrated approach is used to keep the filter submerged and cool, reduce joint counts (and leak points), maintain steady fuel pressure, and cut down on vapour lock. It also means routine servicing won’t include a fuel-filter swap on petrol Splashes. If fuel delivery issues crop up, the diagnostic path in Suzuki workshop manuals points to fuel pressure testing, checking for contamination or water in the tank, and, where required, replacing the complete pump module rather than a standalone filter element.

Worth noting for completeness: in some markets there was a diesel Splash variant with a conventional, serviceable diesel fuel filter in the engine bay. That doesn’t apply to the vast majority of AU/NZ-delivered or JDM-import 2017 petrol Splashes.

When might the in-tank filter/pump need attention? Look for:

• Hard starting, hesitation under load, or flat spots on acceleration
• Noticeably noisy in-tank pump whine
• Low fuel pressure readings against spec, lean running faults, or P0087-style codes

If any of the above shows up, a technician should confirm pressure and volume, inspect for contamination, and, if needed, replace the pump module (which includes the filter/strainer and regulator). When replacing, it’s smart to drain any dirty fuel, renew the tank seal, and check the fuel cap and evap lines. Day to day, using reputable petrol and avoiding repeatedly running the tank near empty helps the in-tank strainer live a long, happy life.

Technical basis: Suzuki Splash/Swift K10B/K12B service literature specifies an in-tank, non-serviceable filter/strainer and no scheduled fuel-filter replacement for petrol models, the owner’s maintenance schedule likewise omits a fuel-filter interval.

FAQs

Does the 2017 Suzuki Splash have a replaceable fuel filter?
No for petrol models. The Splash’s petrol engines use an in-tank fuel pump module with an integrated strainer, so there’s no separate in-line filter to replace during routine servicing.

When should the Splash’s fuel filter be changed?
There’s no scheduled interval on petrol versions. Replacement is only considered if diagnostics show low fuel pressure, contamination in the tank, or a failing pump—at which point the whole pump module is typically replaced.

Can the in-tank strainer be cleaned instead of replaced?
Cleaning isn’t recommended by Suzuki. If the strainer is clogged, there’s usually contamination in the tank and the pump may have suffered. Best practice is to address the contamination and fit a new pump module with a fresh seal.
