Fuel Smell

[Graham-P]

Not sure if I'm alone here as I haven't heard of anyone else complaining, but I get a fuel smell in the cockpit (CanAm) after a few miles.
On Sunday it was bad but we (Simon) discovered a loose fitting
I have blocked the intake on the rear clip to cut down on heat wash and smell.
The filler pipes look a bit cracked on the surface when you squeeze them and it looks like some of it might be coming from the filler caps (I have smeared some Vasaline on the rubber seals to see if that helps)
I plan on replacing the filler necks with an alloy tube connected each end with Samco type hose, but is there some sort of flap seal I could get (like on your normal car filler neck) to stop any fumes coming back up?
I haven't got any fume seals on the back of the luggage containers, not sure how I would go about sealing that area now anyway, maybe expanding builders foam?!? Would that help??
Any one else suffering?

Mine used to make you smell like gas but it turns out at cruising speeds my tune was way off and I was running really rich. Had the tune adjusted and it's great now. Are you running rich?

Could be a bit rich, I'm going to fit an AFR, my dash has a facility in it just got to buy the lamba sensor and LM1 module (I think)
