After replacing my original, Classic (B-reg) Range Rover's fuel tank, with a 'copy' make, petrol now
travels up the fuel filler neck, and leaks through the cap.
I've been told by the garage, that the tank should contain a 'flap' to stop this occurring, which this copy does not have.
However, I've enquired about some original tanks for sale, but the owners say they don't have the required 'flap'.
Are they visible from looking inside the tank nozzle, or perhaps just can't be seen?
Any advice very much appreciated.
