2005 Toyota Land Cruiser Fuel Cap

Yes, a fuel cap is absolutely used on the 2005 Toyota Land Cruiser. Toyota’s own technical literature backs this up: the 2005 Land Cruiser Owner’s Manual instructs drivers to tighten the fuel tank cap until it “clicks,” and the Land Cruiser 100 Series Repair Manual (EVAP system section) describes the cap as part of the sealed fuel system on petrol models. Those sources make it clear the fuel cap is a required component, not an optional extra.

On this model, the fuel cap does a lot more than just keep the filler closed. It seals the filler neck to keep dust, water and road grime out—handy when the wagon spends time on gravel or sand. For the 4.7‑litre petrol (2UZ‑FE), the cap also helps the evaporative emissions (EVAP) system hold the correct pressure and vacuum so the engine ECU can run leak checks. A loose or tired cap can trigger an EVAP fault and a check engine lamp. On the 4.2‑litre turbo‑diesel (1HD‑FTE), there’s no OBD‑monitored EVAP like the petrol model, but the cap still prevents contamination and unwanted odours, and it’s designed to vent correctly for normal tank breathing.

Many Aussie and Kiwi 100 Series vehicles run a sub‑tank setup
