Strong smell of petrol after use (R500D)

[JustCallMeMac]

Hi,

I've recently had my R500D remapped. Not sure if it's a coincidence but about an hour or two after a drive, once the car has cooled down, there is a strong smell of petrol but I cannot see any signs of a leak anywhere and there is nothing on the garage floor. Complete PITA as smell gets in to the house although it eventually disappears with good ventilation.

Any pointers and as I'm a complete novice, please provide as much detail as possible please.

Cheers.

Looks like a leak at the fuel tank end.

Noticed a few drops of petrol on the corner of the frame directly underneath the offside edge of the fuel tank, which had just started to drip on the garage floor. Had a good look around the filler cap, hose and filter assembly but they were spotless and from underneath, around the seal gasket but couldn't see anything obvious. Had a clean up anyway but evidence of the leak soon returned in the same area. Unfortunately I can't easily identify where the fuel is coming from with the tank in situ but I suspect the gasket might be an issue and it's a pig to get to.

Looks like a tank removal jobbie.
