Info
These high volume performance oil pumps feature a 25% increase in flow over stock using Melling's exclusive helical asymmetrical pump gears. The design of the gears provides for a significant reduction in the pressure ripple (pulsing) found in spur gear pumps. The reduction in the pressure ripple improves the wear and performance of the components assembled to the pump. The intermediate shaft and distributor gear wear will be reduced along with improvements in the performance of the distributor, less spark scatter. Included with the pump is the 12550 Chrome-Moly intermediate shaft with steel guide along with a lower pressure relief spring.
