Yep for sure. Back to IP’s though, if there tolerances are so sub micron why do we not have finer fuel filters, and why do they last so long with standard filters, there is a lot of old bulldozers tractors etc that have absolutely filthy tanks in them and they run just fine with these for decades, if oil is fuged and filtered too 2 mic, standard fuel filter is 10mic, what in it that gets past those is the culprit. As I would have thought anything getting past a 10 mic will cause similar issues, is it just the nature of the black combustion material and the constant presence of it?
