Right you helpful brainy lot ....When you remove your fuel tank you have to blank off the 3 balance pipe spigots - right 1. Does anyone know the OD (outside diameter) of the spigots? I have found some blanks for sale on eBay and dont want to order the wrong size ID (internal diameter). Oh sorry .. another question ... 2. If this part number is obsolete (found on the Fowlers website) .. what replaced them? part number T3880631 blanking cap
