i am starting to question the inner workings of the second injection pump. When i first got the cat i did not like the way it ran and assuming it had a good deal of hours, i rebuilt the engine completely.At that time i changed the inj. pump as apparently this new pump had about 4000 hrs on it-which for those pumps is peanuts.I ran the cat off and on for 3 or 4 yrs (300 hrs)and then the smoking problem started.The pump i put on then was the original.( after a amateur bench test).I am therefore suggesting that perhaps the original pump was faulty in the same area as the 4000 hr pump became faulty. My next step will now be to disassemble the 4000 hr pump and see if i can see any problem with the plunger settings because when one thinks of it this is the only aspect of the system where fuel delivery to the individual heads is proportioned.If anyone can expand on this ,please do.
