Eddie: What a crock of you know what. Fleetguard are one of the best filters in the marketplace. I would place them at the top. They told you that story as they cannot get the FG filters at a wholesale price. When it comes to fuel filters for a Cummins there is nothing better than an OEM Cummins Fleetguard. 3 years ago I was unable to source one of my fuel filters from Filter Barn. I went to a Donaldson dealer in Tucson. I installed the filter and drove 300 miles. Kept getting a check engine light. Naïve me never considered it could be the filter. Engine was derating. Went to a Freightliner dealer. Mechanic checked everything. Replaced that Donaldson with a Cummins filter. problem solved. It was sucking air. Tech gave me a big lecture about Donaldson fuel filters. I was still a doubter. 2 days ago I changed my oil and fuel filters. This time I substituted a Baldwin for the Cummins filter. Could not get the engine primed. Removed that filter and it was only 3/4 full. Dug into my filter stock and found a Cummins filter. Again problem was solved. Could this be a coincidence. I suppose but I will never use anything other than a Cummins filter!!!
