    With over 20 different models of 304 excavator it would be nice to know exactly which one you have. Please post a Serial Number.

    This is the Top View of your engine compartment. See #36, right next to that is the refrigerant dryer. Another view of the dryer looking from the rear of the machine. the parts drawings are not very clear but the pressure test ports appear to be on the tubes next to the dryer.

    Thank you so much. Appreciate your time. Found the H port. Still looking for the L port

    Sorry that the illustrations were such poor quality but it’s all there is.
