Hi I've just finished restoring an old VICTA 18. I've got a problem with fuel leaking around the petrol cap which isn't any good for the paint on the tank. I've got 2 fuel caps and they both seem in good order. I've tried both but the petrol squirts out the little vent hole in the top of the cap. This happens very quickly as soon as the mower kicks over. I've even got a clear plastic sealer for between the tank and the cap and this didn't help. The petrol tank is only about quarter full certainly not over full. Any ideas on what might help because this is driving me nuts and already the tank needs repainting.
