In this short time it loaded the filter good. I might do it again for the quick cleanup.
First picture is the day of the install, rest are of the removal after failure.
Seemed to catch stuff, but I wouldn't have expected it to be very effective there.
I'm assuming a pressurised tank (never had one IIRC) works the same as an un-pressurised tank (except being pressurised, of course)
IF this is true, excess fluid expands into the tank through the filter as the radiator heats up, but when the engine is shut off that excess is drawn back into the radiator.
I'd expect crud trapped by the filter on the inflow to be washed off again on the outflow.
What am I missing, and if the tank being pressurised makes a difference, why does it make a difference?
(IF I'm correct in thinking flow does reverse through the filter, a bypass and a couple of non-return valves might be worthwhile.)
