Any merc techs out there that know how often these pricey pair of filters should be changed out? If you look at them , and they look clean, would you stick them back in?
Every year or 100hrs whatever comes first.
A lot cheaper than pulling 8 injectors for cleaning.
Only time I would ever reuse one is if I was out on the water and had to dump the catch cup. I would install a new one when I got back to port though.
