i know you can use the VRO pump as a regular fuel pump and use premix. i know to disconnect the wiring to the vro and diconnect the oil intake and plug it at the vro. my question is this. on my other motor i have 2 older style pumps inline. the pumps are hooked up to the 2 pulse fittings on the crankcase. do i need to use 2 pulse fittings for the VRO? or do i plug one fitting? and hook the other pulse fitting to the VRo?
