I believe that the club shop supplies the glass filter as recommended for use with ethanol, I bought one together with their rubber fuel pipe and hose clip replacement kit.
Yes, the Wedgewood Blue one is mine but you should see a selection of GT6's in several colours as well as Heralds, Vitesses, Stags, 2000s and TRs at The Raven, weather permitting.

Just an update to say that the surgery on the rear hub has worked a treat. So many of the odd noises from the back-end (oo-er) seem to have been eliminated in the process.
Many thanks to the surgery team of Pete and Gully.
