Today I got a new fuel filter and got stuck in changing it. removed the engine cover, then unplugged the MAF from the air box, undid jubilee clip airbox/intake, remove three bolts holding air box two at the front one at the back, now try to remove from engine bay, "tight" or what? disconnect pos battery terminal and loosen bolt holding relays on same side, jiggle the air box and eventually it gave in and came out. Manuals do not explain what a pig it is. Now to the primer bulb, remove top/front cover a doddle, then the back bracket one bolt is easy to see and remove, the other? behind the bulb and hiding, solution unclip fuel pipes from bulb and remove, now we can see the bolt, remove and take the back bracket away. Unclip the pipes on the filter and slide off, undo bolt on bracket, grab the filter and pull up, it comes easy until it fouls the bulkhead, then there is no choice but to tilt it and pull, it does come out!! Refit new filter, pipes and clips, tighten the bracket bolt, replace the bulb bracket (back) connect pipes to bulb and place into bracket, may help to leave one pipe off until in position. replace front bulb cover, jiggle the airbox back into place, the rear hose has a clip,the front one no clip but tight to slide on bolt up, connect MAF cable, squeeze bulb 40/50 times until hard start engine, rev it 3/4 times note a steady tick over, jobs a good un. Wash hands, bathe the scars, if you do not stop bleeding within ten minutes get down thwe nearest A&E.
