easy job to do, i replaced mine when the clips came off from the fuel pump
did you get the bits for service from dave at steels honda? just you'll need to replace the rubber seal from the top of the tank..
first thing is run the tank as low as you dare, the less petrol in there the easier it'll be
did mine by taking the rear seats out first,
use a block of wood and hammer to free the cap up, its on tight and your meant to use some special honda tool to do it, but i managed just fine with a bit of wood :wink:
unclip the connectors on top of the cap, be careful not to snap them though as your meant to replace them too (i didnt) and think about putting the fuel line ends in plastic bags to stop any dirt getting in.
when you lift the cap off (cant remember if filter/pump is attached to cap or not) you'll see the filter/pump set up, held in a white plastic carrier.
obv be careful removing the clips and connectors, from what i remember they were a bit of a pita but take your time and it'll come
have you got a copy of the service manual for reference?
