High-Volume Oil Pump for GM GEN 3/4 LS & Vortec Engines by Melling

The Melling 10296 pump flows 18% more oil than the factory oil pump, topping out at about 8 GPM (versus approximately 6.8 GPM for the factory oil pump). The additional oil volume can improve engine lubrication, but caution should be used when selecting this pump for racing applications as the higher volume can sometimes accelerate oil starvation by pumping oil out of the oil sump faster than it can be returned. We don't recommend using this pump with the smaller capacity oil pans (less than 6 quarts).

The pump also includes a stiffer pressure relief spring, which increases the maximum system oil pressure by 10%. This higher maximum pressure can help negate drops in oil pressure caused by the addition of an oil cooler setup. The stiffer oil pressure relief spring can be swapped out for a factory specification spring, which is also included with the pump.

This oil pump is compatible with LS engines featuring Variable Valve Timing (VVT). This pump should not be used with engines that feature Active Fuel Management (AFM). Engines with AFM require a higher flow pump. See Melling part number 10355.
