Cork fuel tank cap seal

[cpp01]

Helllo,

New member and new to classic bikes. I've just bought a new cork seal to replace the missing seal in my fuel tank cap and despite it being the right diameter (ID + OD) I cannot get the cap to fit back onto the tank.
Is there a special trick I meant to be using or is the seal I've bought too thick?

Thank you for any help you can give.

Regards,

Try soaking the cork seal in very hot water for a few minutes, then quickly fit it to the cap and immediately try to fit the cap to the tank. If it fits, leave it to cool.

L.A.B., thank you for the advice but it didn't work I'm afraid.
Unless there's any other ideas I think I'm just going to have to reduce the thickness of the seal slightly.

Thanks,

What sort of thickness are we talking about here, the seals I,ve bought are around 1/16" thick assuming your talking british bike.
L.A.Bs method is the usual one if the seal is cut from normal size material. I have done this with the seal still soaked and it usually works.

Hi,

Sorry for the delay in getting back to you all. The cork is now in place! After trying the hot water technique described I left the cork for a day or two and it dried out, shrunk a bit and now fits in place without any further 'tampering', a bit tight but good!

Thansk for all of your help.
