Well...I know this may be an astonishing waste of time and energy...chasing the Black Pearl or the Moby Dick...but $700 for two new fuel injectors has me looking to diesel tractor ancestors for bargain pricing... (let's just put aside rebuild for now - been down that road). After too much digging I have determined my M12 Universal is the close (exact?) descendant of the historical Kubota engine Z400. Interesting information, but doesn't seem to deliver the parts cross-reference I would need to make sure I'm ordering the correct Kubota injectors. Anyone else wasted time in this rabbit hole? Should I just stop now and pay Westerbeke their 400% mark-up? Tx. Tom O'Day 28.
