I agree since I have identical situation (Everything clean and no CEL)
Question is...replace the pump now, or wait until is completely goes bad? What is the average service life for 04' and newer pumps? I've heard of them going faster than the older ones with seperate pump and filter since the only filtering being done is inside the tank without a way to service it. I only run 92+ and occasional fuel injector cleaner every fill up or so. I never let it run past 1/2 tank...unless it's between pay-days.
