I m having problems with a fuelpump (Vacuum) on my Aprilia Habana Costom 99-02, Therefore i bought the: Aprilia Scooters Haynes Repair Manual covering the SR50, Rally, Sonic, Habana and Mojito from 1993 thru 2009.
And to my disapointmen the informations in the so called service and repairmanual, was almost non existing, or wrong.
in chaptor 5-4 the manual talks about fuelpump, and in pic 4-2 is not correct, as far as i can see is thefuelpump on the Habana models from 99-02, placed under the battery case.
And not as shown in your manual. And im sorry, i would expect a precise diagram and pictures on the the diferend models your book state to cover.

Need some help here.
