Ok I have to admit to piece of advanced level muppetry! I obviously did not tighten it up properly and on the way to Cadwell it seems to have fallen off. Fortunately it is not used as I have a full flow filter so no damage done but I would like to replace it if possible for cosmetic reasons.
If anyone can help I would be most grateful, I promise I will be more careful in future.
Neil. I have a filter top – but it has a hairline crack in it. This is not obvious but makes it effectively unusable. You are welcome to it if it is will be serving a purely cosmetic function. Let me know if you want it and I will put it in to the post. Regards Mike
