Hi everyone,

I'm getting a powerful whiff of petrol in the cabin when I drive.  It gets stronger when the window is open - any thoughts?

Could be any of your flexible fuel pipes. They fail from the inside due to the ethanol in modern fuel. If they are braided it is even worse as the braiding soaks up the leaking fuel. I'd try the under bonnet ones first if the smell is more obvious when driving, but be prepared to change them all if they are more that 4 or 5 years old.

Also look under the mat/carpet in the boot in case the top of the tank has rotted out.

My 2000 Coupe sprung a huge leak years ago and flooded the engine compartment with petrol. I was very lucky it didn't catch fire, as it came out at high pressure and went absolutely everywhere! I stopped immediately, on a hill, and saw petrol pouring down the hill behind me. My lucky day!

I concur with Tim about it possibly being the top of the tank having rotted away, as Iíve had that on a number of Flavia/2000ís over the years.

Re Ethanol: if you have an Esso garage near you, Esso Supreme 99+ is ethanol free in many areas, but not all - the Esso website tells you which ones.

Thanks everyone.  The smell is only there when the windows are open - therefore the tank option sounds about right. There are no leaks or smells from the the engine bay. The breather system in the boot looks a bit 'Heath-Robinson' - does this cause problems?

I have a strong petrol pong in the boot but there are no obvious pores in the top of the tank. In saying that, it is not unblemished a vapour will find a way through any mildly porous membrane.

In my case, I think it more likely to be the rubber gasket around the fuel gauge sender that is allowing the fumes out. Just need to find a supplier for a new one.

those gaskets are used by contemporary Italian cars like the Fiat 500. Ricambio springs to mind as a source
