A three stage dry sump oil pump with one pressure and two scavenge sections combined with integral alloy front cover. A far more effective pump when compared to single scavenge units since it will always collect oil from the sump whether under acceleration or braking (unlike single scavenge units). Total depth is only 4½” from block face. Pump is driven by an Oldham coupling (supplied) and therefore eliminates the possibility of oil pump drive gear failure. Supplied with BSP threaded ports, all fittings are supplied at extra cost.
