10294, Low Volume, Standard Pressure LSX Oil Pump

Melling engineered this oil pump specifically for the performance aftermarket LS engine blocks with “priority main oiling”. This pump is not meant to support engines with variable valve timing and displacement on demand. The flow rate of the 10294 has been reduced to match the lubrication needs of aftermarket blocks with priority main oiling systems. This eliminates the need to modify a stock pump to reduce its output. Its reduced displacement requires less power to operate. All the features that make our performance wet sump oil pumps best in class have been utilized in the new 10294 low volume pump. In comparison the 10294 is a low volume version of the Melling 10295 performance oil pump.

Features include:

  • Reduced flow output (-15%) as compared to stock oil pump
  • Hard coat anodized aluminum housing
  • Phosphate coated cast iron cover
  • Standard pressure spring installed
  • Includes optional +10 psi and +25 psi high pressure springs
  • Threaded pressure relief nut
  • Uses 7/8” stock bolt-on oil pickup tube assembly
  • Includes O-rings for oil pickup tube assembly

10295, Standard Volume, High Pressure Gen III Oil Pump

Melling improved the standard volume GM LS Gen III oil pump. Design changes to the housing, cover, and components together combine to improve the performance, durability, and capability of the oil pump. Melling has engineered this oil pump specifically for performance LS applications. It can be used in any GM Gen III application that uses Melling’s stock replacement M295 oil pump.

Features include:

  • Exclusive rotor design with improved strength
  • Hard coat anodized aluminum housing
  • Phosphate coated cast iron cover
  • High pressure (+10 psi) spring installed
  • Includes optional standard pressure spring
  • Includes optional +25 psi spring for COPO applications
  • Threaded pressure relief nut
  • Uses 7/8” stock bolt-on oil pickup tube assembly
  • Includes O-rings for oil pickup tube assembly
10295

10296, High Volume, High Pressure Gen III Oil Pump

This pump delivers 18% more flow as compared to the standard volume 10295 oil pump. The design changes incorporated into 10295 have been carried over to this pump. The 10296 pump was engineered specifically for performance LS applications that demand increased oil flow. It can be used in any GM Gen III application with no modifications required to install the pump.

Features include:

  • Exclusive high volume (+18%) rotor design
  • Hard coat anodized aluminum housing
  • Phosphate coated cast iron cover
  • High pressure (+10 psi) spring installed
  • Includes optional standard pressure spring
  • Threaded pressure relief nut
  • Uses 7/8” stock bolt-on oil pickup tube assembly
  • Includes O-rings for oil pickup tube assembly

10355, Standard Volume, High Pressure Gen IV Oil Pump

Melling improved the standard volume GM Gen IV oil pump. To support AFM and VVT components the output of this pump is 33% more than the Gen III standard volume oil pump (Melling #10295). Design changes to the housing, cover, and components together combine to improve the performance, durability, and capability of the oil pump. It can be used in any GM Gen IV application that uses Melling’s stock replacement M355 or M365 oil pumps.

Features include:

  • Hard coat anodized aluminum housing
  • Phosphate coated cast iron cover
  • High pressure (+10 psi) spring installed
  • Includes optional standard pressure spring
  • Threaded pressure relief nut
  • Uses 7/8” stock bolt-on oil pickup tube assembly
  • Includes O-rings for oil pickup tube assembly

10355HV, High Volume, High Pressure Gen IV Oil Pump

Melling has re-engineered the Gen IV oil pump to increase its volumetric output 20% relative to the standard volume oil pump. Design changes to the housing, cover, and components combine to improve the performance and durability of the oil pump. It can be used in any application that uses Melling’s stock replacement M355 or M365 oil pumps.

Features include:

  • Exclusive high volume (+20%) rotor design
  • Hard coat anodized aluminum housing
  • Phosphate coated cast iron cover
  • High pressure (+10 psi) spring installed
  • Includes optional standard and +20 psi pressure springs
  • Threaded pressure relief nut
  • Uses 7/8” stock bolt-on oil pickup tube assembly
  • Includes O-rings for oil pickup tube assembly
