[Mini] Fueling issue

[Frits Schouten]

Hi Anne,
did you check the filter in the tank? It's quit coarse but, over the years, it
can block up.
The point you make that the car runs okay for a few hours after a refill makes
me think that the refill just disturbs the debris around that filter enough to
make it go for a while.
That's my 5cts worth.

Cheers,
Frits.
