The mechanics of changing it are no big deal, I've worked with farm equipment all my life. Our last combine had the fuel filter & water separator located on the right side of the transverse-mounted block, out of sight, out of reach. You had to lean over the engine, peering upside down with a shop light to get to them. Not as simple as it may sound.

It was just the priming that I was concerned with, since, as stated in my first post, some of our equipment needed extra work to get the air out.

But the Cumminsforums.com site was a nice revelation, don't know why I hadn't thought to search for something like that! Seeing the unanimous acclaim for the Baldwin filter convinced me to go that route instead of NAPA or the factory filter from the dealer. Bad part is I had to order it & now gotta wait, no place local carries 'em.

But I appreciate everyone here who weighed in, always can find good info here.
