Parts for your 2013 Toyota Fortuner-Fuel cap

2013 Toyota Fortuner fuel cap

Yes, a fuel cap is used on the 2013 Toyota Fortuner. Toyota’s own technical literature specifies a conventional screw-type fuel tank cap for the AN60-series Fortuner: see the Toyota Fortuner Owner’s Manual (2011–2015) “Fuel tank cap” instructions, the Toyota Electronic Parts Catalogue (EPC) listing a Fuel Tank Cap Sub‑Assembly for this model, and the relevant Toyota Repair Manual sections covering fuel system sealing (including EVAP checks on petrol variants). For petrol models, sealed caps are also consistent with Australian Design Rule ADR 79/03 requirements for evaporative emissions control.

This little cap does more than just close the filler. On a 2013 Fortuner it helps keep dust, water and fuel vapours where they belong, maintains the correct seal so the tank can vent as designed, and on petrol variants it’s part of the evaporative emissions system—so a loose or wrong cap can trigger a warning light. Diesel variants don’t usually run an EVAP leak test, but they still rely on a proper sealing cap to keep contaminants out on rough, dusty roads.

During regular servicing (about every 10,000 km or six months), it’s worth giving the fuel cap some attention. Check the rubber gasket for cracks, hard spots or flattening, make sure the tether isn’t frayed, and confirm it tightens until it clicks. If the gasket’s tired or the cap no longer clicks securely, replacement is the go—use a genuine Toyota cap so the pressure/vacuum characteristics are correct for the Fortuner’s tank and venting layout.

A few easy care tips keep it sweet:

• Wipe dust and grit from the neck and cap seal before refitting.
• Don’t lubricate the seal with oil or fuel, if it’s sticky or swollen, replace the cap.
• If you’ve had a misfuel prevention insert fitted, check cap fitment is still smooth.

Signs it’s time to replace include a persistent fuel smell, a cap that won’t click tight, visible gasket damage, or a petrol-model check engine light with small/large EVAP leak codes after refuelling. On diesels, you may just notice dust in the filler area or a light fuel odour after drives. Either way, a fresh, correct-spec cap is an inexpensive fix that protects the tank, keeps the cabin free of fumes, and helps the Fortuner pass emissions checks where applicable.

Quick fit guide:

1. Open the fuel door and remove the old cap, inspect the filler neck lip.
2. Seat the new cap squarely and tighten until it clicks.
3. For petrol variants with a warning light, drive a few trips after refitting, clear any stored codes if required.

Popular questions about 2013 Toyota Fortuner fuel caps

Will a loose fuel cap cause a check engine light on a 2013 Fortuner?
On petrol models, yes—a loose, missing, or incorrect cap can set EVAP leak codes and light the MIL. Tighten until it clicks, then allow a few drive cycles for the system test to pass. Diesel models typically won’t trigger an EVAP fault from a loose cap, but you may notice odours or dust ingress, so it still needs to seal properly.

Are Hilux and Fortuner fuel caps interchangeable for this year?
Many AN60-series Fortuner caps cross over with contemporary Hilux models, but variations exist by engine and market. The safest bet is to match by VIN in the Toyota EPC and use a genuine Fuel Tank Cap Sub‑Assembly to ensure the right seal and relief characteristics.

How often should the fuel cap or seal be replaced?
There’s no fixed interval—inspect at every service. In normal use, a cap can last many years. Replace at the first sign of a hardened, cracked, or flattened gasket, a cap that won’t click tight, recurring fuel smells, or EVAP leak faults on petrol variants.
