Fuel filter plug on Cat785C & Cat 789C

If the fuel filter is plugging the contamination is coming from somewhere. Could be your fuel supplier, filling practices and I have even seen sabotage from disgruntled employees. My suggestion is to cut open up one of the filters and see what is actually plugging the filters. If you can't identify it then send one to a lab and have it analyzed. Once the contamination is identified the source can be tracked down and eliminated.
Hi, we have recently sampled the fuel tanks on a complete mine site and the results indicated there were 25 % of the machines with biological growths in the tanks, these growths require water to survive so we found that;
Tanks breather were not being replaced, replace tank breather every service.
Water checks were not performed, Drain water off every service and if found check for water weekly.
We found that fuel filters were serviced but with the presence of water and machine heat if the tanks breathers were not serviced there was enough organic debris gaining access to start new growths,
