I was recently changing 3 FJB0 units to FJB1s
and I tried cleaning the others - degreaser and compressed air. When I looked into the input end of the old units they were packed with fibres - I wasn't sure if this was some kind of filter so didn't want to mess too much. The new units arrived and I noticed they were clear with a brass gauze as a filter, so I made a hook from a paper clip and went about picking out the old units - the pictures shows about 1/2 of what came out of each unit. Is it possible the one shot pump filter is made of felt or similar and this is what has gradually been blocking these up?
