What brand/type filter did you use? Use of something other than an original Racor coalescer has caused pressure drops and even stumbling in some trucks (even "good" brands like Wix). I haven't personally seen it because my baby is still on the factory Racor at about 30k and going strong and I plan to put another Racor in its place.
Off the top of my head you should be using an ACDelco part # TP3012? Not sure but it's easy to google... 4 micron depth pleated synthetic micro glass filter made by Racor.

FWIW the reported LML stumbling and dropping fuel pressure was Mike L with a brand new WIX fuel filter. Said it would stumble and hesitate at 80mph and full throttle (highest fuel flow demand), then the fuel filter life would instantly drop to 0% and I believe throw a code...
Never seen it first hand but I can tell you there aren't many filters with higher quality filter media than the factory Delco TP3012 and there's no way that WIX can have one balance the same 4micron single pass efficiency and still match the flow rate of the factory filter inside that tiny volume plastic can. It seems they chose to sacrifice on the flow rate.
Also FWIW I'm a chemical engineer by education and I'm pretty commited to the factory Delco or Racor 4micron fuel filters. No reason to change until you start upping your power demands, and actually I've never changed mine yet at 33k + miles. Some people may think this is irresponsible, but alot of people have a hard time accepting that modern off-the-walmart-shelves oil can last 18k miles towing heavy and modern synthetic microglass filter media can filter smaller particles AND flow more fuel AND hold more dirt before clogging. Trust the science and 10yrs of development behind the LML, the filter and fluid life monitors have been proven accurate with factory or higher quality equipment :thumb:

Well this is on my boss'struck ant I'm not Gona take a chance going back to ac delco filter Wix plastic is junk IMO. And that's what I'm sticking with.
