Help! Fuel leaking from charcol canister

[mrv8]

When ever I fill my car up, or the temperature heats up, I have fuel start leaking from my charcol canister. Any help to fix this would be greatly appreciated.
Thanx, Anthony.

check your tank breather pipes and petrol cap for blockages and damage to the lines .

I had this issue when I replaced the fuel tank, was supplied the wrong tank, 1 extra fitting, anyway.. and had the return line from the canister on the wrong breather pipe on the tank. Sending fuel into the canister and spilling into the bay. Very dangerous!

Any recent work done to vac lines, or painting the fuel tank out of the car?
