I replace them every year whether Racor
, CAV or whatever. The filtering element structure collapses over time and they stop being effective. I change more often, if the engine
gets more use. The same philosophy in my own boat and in the boats I work on.
Every time I change the filters I find quite some deposit there, be it in the element, in the bowl or in between the many parts
You can't have the diesel
too clean. You can only have it too dirty.
