    Fuel filter replacement

    Anyone actually replaced their's yet? I know that it's inside the tank along with the pump so a pain in the rear end to get to and you need a new gasket/seal, hope that it does it's job properly or you'll have petrol leaking onto the engine!

    What a stupid design really, would have been safer and easier to leave these items outside of the tank like they have been from the start.

    The workshop manual mentions a piece of foam/baffle I think but the European/UK bikes don't have it, anyone familiar with this, what does it do exactly?

    Good questions.  Hopefully someone with experience will chime in.

    I also wondered about the baffle/foam.  If it is not there on all, why is it on some?  Is U.S. fuel different than Europe?

    We have 10% ethanol in our fuel here now.  Well in most places anyhow.  We also distill for more gasoline from crude and end up with less Octane than the other side of the pond.

    Thanks for the info Karl, any idea on if that's anything to do with the baffle being fitted??

    No clue, but ethanol is a very aggressive solvent for a lot of materials and plays hell with a lot of "older" fuel systems that are not designed for it. The baffle should prevent fuel sloshing around and reduce weight transfer and foaming issues.

    But fuel sloshing isn't a reason to change it, and it would be consistent across the board.  I wonder if this refers to a 'pre-filter' type thing (a sock if you will) that is in front of the pump.  Maybe due to the ethanol cleaning ability?
