"If you are standing on the starboard side of the engine, you can follow the fuel line to the first filter, which is a low pressure filter (a white plastic cylinder shaped) , at the bottom right as you look at the engine from the side. The high pressure filter is actually inside the vapor separator, which is just to the left of the low pressure filter. On the right end of the vapor separator., there is a cover held on by three screws. In the center of the cover is a bolt. Use a 10mm wrench to loosen it to relieve the high pressure in the vapor separator. Be sure to put a rag over it, and use safety glasses so you do not get a shower of fuel. Once pressure is released, you can remove the three screws and remove the plate. The high pressure filter is inside. The parts you will need are 16911-ZY3-010 Strainer (high pressure filter), 16078-ZY3-000 O RING (It will loose its shape when the) fuel hits it.)and 16900-SR3-004 fuel filter (low pressure)...total cost of about $60.
You should also drain the vapor separator into a glass jar to see what your fuel looks like. There is a nipple (drain) on the bottom right of the vapor separator and there is a drain screw just above the nipple. You just have to back the screw out some, put a little hose on the nipple and tilt the motor up to drain it.
You really should buy a Honda Service Manual. It will show you pictures of all of this and how to do it."
