Faint fuel smell
Right just got the TF on the road this week after doing a few (!) bits to it - none engine/fuel related. Anyhow I get a faint petrol smell if I use a large throttle opening which seems slightly strange to me. Since I have had the hood down each time I am not sure if it is unburnt petrol from the exhaust or something else. Just to add to the issue I have a lumpy idle but plan to change the plugs which may sort this out. In all other respects the engine runs fine just this smell is odd. Any ideas??? (It has just passed the MOT with no emission issues).

Re: Faint fuel smell
Check that the breather hole on the fuel cap isn't blocked. If you unlock the fuel cap after a drive do you get a big rush of air? This will give an indication ~ as you use fuel the space should be replaced by air; if the hole is blocked air can't get in.

Re: Faint fuel smell
Don't know asI haven't done many miles in it. It happens under acceleration and not when stationary. Presumably it is easy to clean the vent in the cap?

Re: Faint fuel smell
Interesting...I also have a faint petrol smell and when I open the petrol cap there is a rush off air so the hole on my fuel cap must be blocked...I didn't even know there was one but I will clear it and see if that helps!

Re: Faint fuel smell
The tank is supposed to be sealed and has a release valve, it is normal to have pressure released when opening the cap
