Although my system runs well with the multiple Walbros I just came across the Asnu FP580X (E85) pump. By comparison it is only pulling 12.5amps at 6bar and 7.7amps at 3bar.

Nice pump, but it may be difficult to find a replacement. The Walbro's are everywhere.
VaporWorx can PWM the Walbro 450's as well, dual and triple setups. That limits the power to the pumps to only what's needed, so if the engine does not need all that fuel, the controller will throttle the power to the pumps to only what's needed.
