Petrol Smell In And Out Car

[gt4WRC]

For the last two days there has been a petrol smell inside the car, cant source as yet where its coming from, and a really strong one from outside, not from the engine, but from the fuel cap/door area.

There is no visible leak on the floor around the car at all, but this morning went out to check incase it was just a spill and i went under the car, no leak from fuel tank, but under the wheel area under the fuel cap there is a strong smell. Checked the cap itself and its on correctly, not cross-threaded or anything.

Any idea what this could be from?

Thanks

could be a faulty filler cap, i would also check the pipe from the cap to the tank

itll be the filler neck pipe look underneath they tend to rot near the tank end its a replacable part from toyota i think they were about £28 iirc if its just breather part you can fix with a bit pipe smae diameter and clips
