Yep, Fuel filter thing is total BS and don't forget about our "capless" gas tanks. Tell me extra stuff doesn't get in there. And why don't they put a door lock on it to keep the Chevy guys from putting anything in there

RE plugs.. I heard they got them fixed on the 5.4 by 07 or 08. I made the mistake of changing my plugs in my VW rialta RV. didn't seat the plug wire on all the way and the backfire blew a hole "through" my cat's catacomb thing. Had the darn Check engine light go off every 150 miles after that. But my MPG did increase by about 2. Anyways, I won't change my plugs until I notice any MPG drop, misfires or bad ideling!!

The lifetime filter works by being flushed out each time the truck is shut off. The fuel back flows a slight amount to flush the debris into the tank. And as far as the filter goes, when is the last time a filter fixed someone's concerns. I bet it hasn't been for a long time.

Also the make locking caps for the capless fuel system if you were worried for some reason. They also take a gas nozzle or the special funnel to open them.

Also the plugs were fixed in 09 with a head design change using normal plugs

twiggy, I changed my fuel filter and my MPG increased a bit. Hard to tell if that was the complete issue but it was some of it. A worthwhile $18 investment which included the tool to change it. Wouldnt you rather have it outside the tank so it can be a quick easy cheap fix rather than having to drop the tank and for most take it to a dealer or shop to have it done? A $15 job becomes a $500 job. Thats the way new cars are going these days though guess we should all get used to it.

Let me take a different approach at it. The dealership and Ford motor company are two different things. Ford wants to make a zero maintenance vehicle because it saves you money and if you save money that makes you happier with the truck. That is why Ford uses up to 10000 miles on their oil changes now. Axle fluid is lifetime service. Fuel filters are life time. Plugs at 100k... Ford wouldn't do all that and more if they didn't have faith in it lasting.

I guess the question is, "whether or not the changes that Ford makes to their trucks really last as long as they say they do". Example: In my 07' 3V Triton, they list 100K for the plugs. Given the history and design on the plugs, 100K is not realistic. More like 50-75K... Unfortunately, what happens some times, is that companies change things to appeal to a mass market and end up hurting the quality of their product.

What do you mean When you say flush the debris?

Back pressure pushes debris back into the tank and keeps it from entering the fuel system. The debris is trapped in your tank FOREVER! Hopefully, you don't get much in the line of debris in your tank.
