none of the offerings are for bikes with fuel pumps. its much more difficult to have an even mounting surface for a fuel pump then to put in a bung for a petcock.
monster tanks also have a fair amount of variation under the tank for airbox and battery variations. It would take a lot of work on their end to figure out what space would be needed to fit the largest amount of tanks without diminishing capacity of the tank too much.
the only way I can imagine it being done on a grand scale would be to make a middle ground shape that would fit a bunch of bikes with interchangeable plates to mount the various fuel pumps. the best way to do it would be to sell it in conjunction with TPO's beast kit to get the most volume out of it as well as reduce the variation between models.
if I was having one made I would also switch to a speedcell or similar mini battery and make a new bracket for the ECU/battery to get even more volume. probably wouldnt make it look like a stock tank either...
maybe its time to call this guy...
