Uses 5/8 diameter press fit screen, Features exclusive asymmetrical helical gears, Has a high volume output- 25% more flow than stock, Offers a significant reduction in pressure ripple (pulsing), Includes mounting tab. These high volume performance oil pumps feature a 25% increase in flow over stock using Melling 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.High volume output- 25% more flow than stock. Significant reduction in pressure ripple (pulsing).
Reduction in torque ripple in pump drive. Improved distributor operation- reduction in spark scatter.Improved distributor gear and intermediate shaft wear. Includes 12550 chrome-moly intermediate shaft with steel guide.
