Does anyone know which fitting on a 99 sportster oil pump is the return and which one is feed from oil tank, and last which one goes to the oil filter. Only 3 fittings on pump.. I have the model that has oil pressure switch in oil filter housing. Picture would be awesome... 2 of the fittings are directly across from each other on the pump, and the other is a elbow type fitting higher up on pump.. Any help is greatly appreciated
