Thanks VOC spares - this has been a problem for many years and I have been modifying the paper filters by taking one end off, enlarging one end hole to one and a quarter inches and fixing the end back on with a thin rubber ring outside with silicon sealant on the card board side inside.
The total length of the filter is then reduced to a little under three and a half inches and the filter then can be put in with the end cap oil tight and seals hopefully against the end of the filter chamber.
I am not too happy with this "bodge" because even with great care it is possible some bits could get into the filter from the work, but have not had any problems for more than 10 years.
However now the older style felt filters are available I shall use these in future and go back to standard.
