Parts for your 2022 Suzuki Splash-Fuel filter

2022 Suzuki Splash fuel filter — what’s actually fitted and what matters

Technical documentation for the Splash shows there isn’t a separate, serviceable inline fuel filter on the petrol model. The Suzuki Splash/Ritz workshop manual for the K12B petrol engine lists the fuel “filter/strainer” as part of the in‑tank fuel pump module, with no scheduled replacement interval. The Suzuki Electronic Parts Catalogue (EPC) diagrams for Splash/Ritz confirm the same module‑integrated setup. Sister‑model references (Opel/Vauxhall Agila B technical information) mirror this design, noting a non‑serviceable in‑tank filter for petrol variants. For markets where the Splash was sold with the D13A 1.3 diesel, the manuals specify a conventional, serviceable diesel fuel filter in the engine bay.

The verdict for a 2022‑registered Splash in Australia or New Zealand: the typical K12B petrol car doesn’t use a separate, replaceable fuel filter. Any “fuel‑filter” listing for that vehicle generally isn’t relevant unless it’s the diesel version. Instead, the filtration is handled inside the tank by a fine strainer within the pump assembly. That setup is designed to last the life of the pump and only gets replaced if the module is removed due to pump failure or confirmed contamination.

Why Suzuki went this way comes down to packaging, reliability, and emissions control. A returnless fuel system with an in‑tank filter reduces vapour emissions, shortens fuel line runs, cuts down potential leak points, and keeps the filter submerged and cool. It also reduces maintenance complexity—there’s no periodic filter swap on the service schedule for the petrol Splash.

• What owners should do instead: stick to quality unleaded from reputable servos, avoid running the tank near empty, and service the tank breather/EVAP components as required.
• When to investigate: hard starts, lean running fault codes, noisy pump, or a noticeable loss of power under load can point to a restricted in‑tank strainer or a failing pump.
• Remedy if contaminated: technicians inspect fuel for water/rust, clean the tank if needed, and typically replace the complete pump module rather than the strainer alone.

Note: The Splash nameplate wasn’t produced as a new global model in 2022, some vehicles are later registrations or carry‑over stock. The fitment logic above follows the factory service manual, EPC data, and equivalent sister‑model documentation.

Popular questions

Does a 2022 Suzuki Splash have a fuel filter that can be changed during servicing?
On petrol K12B cars, no. There’s no separate inline filter—filtration is built into the in‑tank pump module and isn’t on the service schedule. Only diesel D13A versions use a replaceable engine‑bay fuel filter.

How often should the Splash fuel filter be replaced?
Petrol K12B cars don’t have a scheduled fuel‑filter replacement. The in‑tank strainer is only dealt with if the pump module is removed or replaced. Diesel versions follow a periodic interval outlined in the service manual, typically every service cycle specified by the market.

What are the signs the Splash’s in‑tank filter or pump is clogged?
Common clues include long cranking, hesitation under load, flat spots at higher revs, and pump whine from the tank. A technician will check fuel pressure, scan for lean codes, and inspect for contaminated fuel before recommending a pump module replacement.
