There is normally an overflow pipe from the top of the filler pipe which
lets out excess fuel in the event of overfilling, fuel (in common with most
liquids) also expands when it gets warmer so that is sometimes the cause of
excess fuel 'leaking' out of the overflow pipe. Also when your car goes
round a corner it leans and fuel can in theory reach the top of the pipe, if
your filler cap is faulty it could leak slightly, is there any fuel outside
of the filler cap, in the recessor on the bodywork? This was a problem with
old Metro's and caused accidents as the fuel leaked onto the tyre. If its
the filler cap a new one should be pretty cheap.
Is the nozzle normally right in when you fill it it? If not the cut off
would be delayed resulting in it overfilling, also it cuts off for a reason
and squeezing in an extra 27p is actually overfilling the tank. This sounds
a likely cause as it was overflowing before you had left the garage.
If your'e not sure that overfilling/faulty cap is the cause I would get it
looked at professionaly as the consequences could be disasterous, an
independant garage could be more competant than a dealer with this kind of
Thanks for the reply.
I don't normally squeeze any more petrol in the tank but for some reason I
thought I'd round it off!!! ;->
Anyway, it always smells quite strong of fuel when I fill it up. I try to
get the nozzle fully in but perhaps its not.
Its in for a service tomorrow and they are supposed to check pipes, rubbers
and hoses so I'll have to see.
I'll post back with news......better not need a new tank!
