Ive been leaving it run hours at a time I had a "diesel man" look at it...$100 ah hour he said its a good machine just smoking blue smoke now to keep running new fuel through it .... he also put injector cleaner in it...said keep running it...my question will that help should I keep just adding new ...

Any suggestions on what else to do to get this dozer back to work???

This wont let me include a photo of the filter I replaced but it has
JOHN DEERE
AR50041
FUEL FILTER ELEMENT
18786
STANDYNE AUTOMOTIVE CORP.WINDSOR, CT U.S.A.
PAT. NO.3,591,004

stamped on it.
where would a second filter be located?

OK so a buddy put old diesel in my 450 JD Dozer... It started running bad immediately. loss of power white smoke ext so I drained the fuel tank I put it in clear plastic jugs and about 2-3 inches in the bottom looks to be sludge...so I put all new fresh fuel in it and changed the fuel filter. NO HEL...

How do you check the oil level on a 450 dozer where's the dip stick????
