Its not that hard Simo, but getting the mechanic to do it is probably the best bet. Just make sure your fuel tank isnt full when you do it. Basic steps are - Remove back seat - Pry open lid in middle of floor. - Unclip the fuel pump, and unscrew the pump/filter unit. - Remove unit, and look into the fuel tank and see what it looks like, any crap in the bottom is a bad thing. - Replace new parts with old, dont forget o-rings and the other seals. - Place unit back into tank, do up the screws, plug it all back in. - Turn ignition to on, leave for a moment for the pump to prime, then start the bugger up. Easy!
