First fuel filter change-successful!
And another satisfied customer of the XD forum! Opened the water drain, went up and cracked open the engine filter housing (which really drained out that upper and lower housing!), changed the engine filter, then changed the lower. MAN! That lower housing is scary tight but easy constant pressure got it started, filter stayed up in the cavity and had to be eased out, so I guess the O ring on it was working. But that O ring on the drain housing was loose and floppy after inspection. Got it all buttoned up, 2 prime sessions and voila, starts right up!
