drfrisker Posted March 28 Report Share Posted March 28 My tank leaks very slowly at the bottom, wondering where I can find a suitable replacement, it isn't listed separately in the parts manual. I see the newer cotas use two o-rings but I don't think I'm that lucky. Quote Link to comment Share on other sites More sharing options...
marky boy Posted March 28 Report Share Posted March 28 They are available and listed separately. 17574-NN4-000 Around £25 from Honda. St Blazey MX will sort you out with one. 2 Quote Link to comment Share on other sites More sharing options...
drfrisker Posted May 12 Author Report Share Posted May 12 Gasket was fine, but found rust in the fuel bottom assembly to the point where it was porous. Cleaned it up and lined it with kbs coat I had lying around (my first choice is caswell epoxy tank liner) fuel pump might be on it's way out now Quote Link to comment Share on other sites More sharing options...

Obviously, the aluminum tank is fine. The bottom hat that holds the fuel pump, allows the wiring and pressurized fuel to pass through is a mixture of coated steel and some brazed or welded parts. The steel had become rusted and porous so it needed to be replaced or coated and lined. Not the first Honda fuel component I've come across that needed to be lined. Overland Trail mentioned that honda is discontinuing the gasket/packing going forward Edited 8 hours ago by drfrisker Quote Link to comment Share on other sites More sharing options...
