    We want to run new braided fuel lines on this old KW.
    N14 Redtop Cummins
    The cooler plate for the ecm.....
    Once lines are detached, is it ok to just use air and blow the plate out (I assume you would apply air pressure from the input side) to be sure that any debris in the cooler plate is removed.
    Or is this a no no?
    Would you use water?
    Is there a certain way to go about it?
    The plate itself, while old, looks fine and is not leaking.
    Any advice welcome.
    Thanks!

    There is a 1 way check valve in the outlet fitting. Not all N14 had these. Take pocket screwdriver and gently pry off at flare end. End, check valve and spring will come out into your hand.

    Thanks....so after you remove the spring and check valve it is ok to use air pressure to blow the unit out?
    No harm there?
