Yes, i'ts the fuel pump.
Andy Rouse preferred not to use electric fuel pumps, so he fitted the mechanical unit shown, driven off the inlet cam pulley by a toothed belt (looks like a miniture cam belt LOL):
Its a backup, a failsafe to get back to the pits etc incase the proper ones die, used on most RS500 racers, and most top flight racers of that age (GrpA R32GTRs for example).
They do run proper fuel pumps too, as that pump hasnt a hope in hell of flowing the amount of fuel needed.
