Parts for your 2020 Suzuki Splash-Fuel cap

2020 Suzuki Splash fuel cap — purpose, care and when to replace

Technical references including the Suzuki Splash Owner’s Manual (EU, Refuelling/Fuel Filler Cap section), the Maruti Suzuki Ritz (Splash) Owner’s Manual, and the Suzuki Electronic Parts Catalogue for RS413/RS415 list a screw-type fuel tank filler cap with tether for this model. Suzuki did not specify a capless filler system for the Splash. So, even where a Splash is registered as a 2020 vehicle (late registration or import), a conventional fuel cap is fitted and absolutely relevant.

The 2020 Suzuki Splash uses a standard screw-on fuel cap that does more than just keep the petrol in. It seals the tank to help the EVAP system manage fuel vapours, stops dust and water getting into the neck, and maintains the right pressure so the engine control system can do its job. When the cap isn’t sealing properly, owners may notice a whiff of fuel around the rear quarter, a spill at the bowser, or even a check engine light for a small vapour leak. Tightening until it clicks a few times is the go, if it won’t click or the seal looks cracked, it’s time to replace.

As part of regular servicing, it’s smart to give the Splash’s fuel cap a quick once-over. Wipe the threads and the rubber O-ring with a clean rag, check the tether so it’s not about to snap, and make sure the flap area is free of grit that could nick the seal. A genuine or OE-spec vented cap designed for the Splash/Ritz (RS413/RS415, K12B) will keep the EVAP system happy and avoid nuisance warnings. Universal caps can be hit and miss, especially if they’re the wrong venting style.

Replacement is straightforward: open the fuel flap, remove the old cap, inspect the filler neck lip for damage, then fit the new cap and tighten until it clicks. No special tools, no dramas. If the vehicle has recently thrown an EVAP leak code, clearing the fault may take a few drive cycles after the cap is correctly refitted. For high‑kilometre or harsh‑environment cars, refreshing the cap every few years is inexpensive insurance against vapour leaks, hard starting after refuelling, and wasted time at inspection.

• Replace the cap if the O‑ring is flattened, cracked or swollen.
• Replace if the cap no longer clicks/tightens or the tether is broken.
• Use petrol‑resistant rubber only, avoid silicone greases on the seal.

Is the 2020 Suzuki Splash capless?

No. The Splash uses a conventional screw‑type fuel cap with a tether. This is shown in Splash/Ritz owner’s manuals and supported by Suzuki’s parts listings for RS413/RS415 models.

What fuel cap fits a 2020‑registered Splash?

A genuine Suzuki or OE‑equivalent vented cap specified for Splash/Ritz RS413/RS415 (K12B) is the right pick. If unsure, matching by VIN with a parts supplier avoids the wrong seal profile.

Why did a check engine light appear after refuelling?

Often it’s a loose or worn fuel cap causing an EVAP small‑leak fault. Refit and tighten the cap until it clicks several times, if the light persists after a few trips, the cap or EVAP system may need inspection.
