I am dumping the VRO, going to premix and either want to rebuild my VRO pump (blocking off the oil side) or get a dedicated non-VRO fuel pump. I am puzzled as I see a number of fuel pumps pictured online that are claimed to be compatible with my 1988 110 hp Johnson but they only appear to have two nipples. Is that possible? They must have inlet, outlet and pulse ports, correct?
