I bought this TEF20 a project to make it as new as I can.When I undid the oil filter it struck me that there are parts missing after unscrewing it from the holder. The repair manual is badly illustrated when i compare what i have to what it should be. Can anyone be kind and point to me what's missing and where i can buy the missing bits and also is there latest equivalent so i get rid of this cartridge with a screw on type

Hi
In the Ferguson club Journal No. 115 you will find an article on what should be in the filter housing. There are also repair kits available on the internet with replacement parts, try searching, oil filter housing repair kit.
