The problem is usually the tank and not the cap.
Drmini cut the neck off his tank and fitted a repair kit

Does the seal have much pressure on the filler neck when you screw it on? |

Yeah I rinsed the tank a few times with hot water, then filled it with cold water to the bottom of the neck while I oxy welded it. The weld is inside the rubber grommet so can't be seen. |

Often the cork seal is crushed and doesnt allow it to seal. Get the centre from the chest cover cork gasket from a small bore gasket kit and cut a new one seal for your cap. initally it will be tight but it wears in. The cooper s chest-cover cork is too thick. Brenton |

Many tanks have damaged bayonet lugs in the top (or the sealing face bent) from bogans levering locking caps off to pinch fuel. Neoprene rubber is a better seal than cork, which tears up from the cap being turned. You can buy the right size neoprene seals at a boat shop (they are used on S/S cruisetanks, which take the same cap size as a Mini). 
[edit] I'm talking Mini sedan tanks here, your woody's neck may be different diameter (I've never measured one). |
