Peter Forbes did suggest a filter that fits in the existing lister filter housing. It was on this site and I copied it and it has worked very well for me over the years cheers Peter.
The one I use is a Coopers filter number AZF 058 and is available in the UK. I buy 6 at a time and they cost me £5.20 each.
Also Crossland 457 or Fram C11860PL are the same filter, and I am sure there will be others from other filter manufacturers.
This is a picture of the adapter I made to fit in the top housing
This is made from a 18mm threaded hydraulic fitting with the thread machined off at one end to be a nice fit in the rubber in the top of the filter.
The thread in the lister housing is 18mm metric because Lister used Bosch fuel injection equipmemt. Any firm that make hydraulic hoses can supply the 18mm adapters.
On the bottom end of the filter I use a 8mm stainless steel nut and bolt with stainless steel body washer and a few small washers to get hight correct. This fits in the hole at the bottom of the filter and makes a good seal.
The other thing I did was to replace the pipe from the filter to the injection pump with a rubber pipe it saves having to undo the steel pipe on the pump and filter housing every time you change the filter.
Heres a few more filter numbers for the same filter.
