cat d5g AGG00655 or AGG0655.... Its been a on going thing I learned today ..all equipment there on site is fueled from a 1000 gal tank into a 100 gal tank to equipment none of them have any problems at all..d5g fuel filters have been changed 3 times by foreman at job site...its always fueled up at ended of day and always messes up at 7 to 9 hours of running ...some times pushing dirt Sideways and up and down on inclines....I don't know if on flat ground yet I'm texting foreman now ...
I haven't had time to check sis for screens in fuel lines or tank
Or get trouble codes yet its a 3 hour one way ride to job site

G..G..G..Granville.........!! Fetch your cloth.
How long has the tractor been on that particular job site..? Personally if there is other equipment being fuelled from the same tanks then I fail to see how the refuelling process is the root cause of the problem.
Has anyone tried draining the water/sediment from the fuel tank like they are supposed to do weekly..? Just for sh1ts & giggles..........

They will trap trash in the elbow from the fuel tank to the incoming side of the filters. It's a common problem.
Right on the money ...I pulled water and fuel filter assembly has primer on top of it so I took it a part and its was loaded with rust ,pine needles etc
Cleaned it up and back to pushing dirt till I can get it back to shop and drain tank and see how bad it is inside
