Normally you don't "check" a fuel filter, you just replace it as a precaution. The fact that the fuel pressure is still within specifications at a 25,000 mile inspection doesn't mean it won't finally become restricted enough to cause a pressure loss at 26,000 miles. Besides, with all the bad internal lines that have been experienced it makes sense to go in there and check it all out.
Many/most maintenance interval items on all kinds of things like cars, bikes, lawnmowers, etc. aren't based on going as long as physically possible between changes (like waiting for the spark plugs to misfire repeatedly, or the air filter to clog up enough to cause a rich mixture, or the brake fluid to absorb enough moisture to drop the boiling point 100°). The intervals are designed to allow the fluids and filters to be cleaned or changed before problems occur. That's why they call it preventative maintenance.
If I read d00d's post correctly, the dealership just checks fuel pressure and if still in spec they don't change the filter? Bad idea in my opinion.
