There is no Honda recommendation for fuel filter replacement. The filter is automotive in design and execution (immersed in the lower tank) and some of us have replaced the filter when replacing the pump. If you want to replace the pump with OEM it comes as a unit with a filter but the filter is available separately. I replaced the pump and filter around 120,000 miles just because I didn't want any problems out of the road - I wasn't having any problems. I went OEM with the filter and aftermarket with the pump. I do not think anyone has sourced an aftermarket filter that fits but pumps are easily found.
