Replace it when it becomes cracked or frayed.
Replace them every 100,000 miles.
Honda recommends every 100,000 miles.
you should only need to replace your fuel filter about every 45-60k miles. Check your service manual for scheduled maintenance.
Under normal conditions I recommend you replace it every 30,000 miles. Dusty conditions more often.
Only when it fails. 250,000 miles would be average.
often 400 flat if he wont do it for that someone else will
Not often if there tarting to wear and tear you should replace them.
The regulator is internal to the alternator! Just replace the alt. The alternator has an internal regulator that can be replaced by itself; however, when there is an issue with the alternator, it often involves diodes in alternator instead of or in addition to the regulator. better repair shops will often take an alternator to an automotive electrical repair shop for same-day rebuilds, with the value much higher than a cheap rebuild in a chain parts shop, and hundreds less than a dealer replacement. You want Bosch or your own Bosch rebuilt
According to Honda specs the serpentine belt, surrounding belts, and water pump should be replaced very 105,000 miles. I know people wh waited past that point and their Honda is now in the junkyard after the belt broke and the engine parts flew together.

Usually never - not a maintenance item However - if you notice any cracks, tearing or wearing down on the rubber (since all rubber goes bad no matter what), then you should replace it/them.
