Petrol Leak

[Frenchtvr]

Hi all, i have an irritating problem in that whenever i fill up with petrol (which is quite frequently) after about 5 minutes or so i get petrol pumping out via the filler cap and down the rear wing. This is made worse by any left cornering. Anyone any ideas as to a solution.
I was hoping ot sort it before i drive back to the UK this weekend.
Cheers,

Mick

sounds like a blocked breather pipe !

It's around the back of the tank - I think !

Transfer pipe blocked?

[Frenchtvr]

I had the tanks out over the winter and all the pipes are in good condition and unblocked. One thing i did notice and checked again last nigt is that i don't appear to have a breather pipe from either of the tanks. All the hoses connect to somewhere else. On the filler neck there are two pipes, the larger filler pipe and a smaller breather type pipe that goes to just below the cap level, presumably to let air escape whilst filling the tank.

this happened on my 280 2+2
I put a bigger breather pipe on (left side of tank) and fitted a chimaera filler cap
Job done
What does happen now (pulled a couple of times on track days) is under sever cornering forces the petrol can leak out of the bretaher!

Just dont follow me with a match

Cheers for that gemini, if i can find a place for a breather i'll fit one, in the meantime i'll get a Chimera filler cap.

Discussed last week. Yes there is a breather from the filler cap. Yes it will spill fuel unless you fit a one way valve in it on a track day on LH corners.

Frontera's have a non return valve on their breather as a matter of interest...

do they? must go and look

Thanks chaps, bit more investigation required tonight i think. I think mine leaks more from the actual filler cap, funny type of double cap arrangement on mine. Will take off the interior trim and try and find the breather pipe.

Not just Fronteras... all modern cars including Griffi and Chimparis, Cerbs and Tuscans etc.
