Thanks for the supporting info chaps cheers

I can confirm that my old 4/4 had a simmilar shoe filling issues and was fitted with exactly the same cap. However when Stev Simmonds swapped it for a Monza type it was alot better. flag

So I was wondering if anyone had experience of Steve's Aero tank cap see Simmonds Aero Tank Cap sherlock
