The fuel pump is extremely expensive and unfortunately it is also fairly often the reason for a break-down. In our experience especially the BS6/Euro5 models seem susceptible to this. In Europe prices vary but up to 400 Euros have been quoted for an OEM replacement of the entire fuel pump.
In almost all cases the electric motor is broken – the rest of the pump is just a plastic housing and unless you break that there really is no need for a replacement (our set includes a new filter element as well).
Exchange of the motor takes 10 minutes and one small screwdriver once the tank has been taken off the bike and the pump removed.
