Product Description
Melling Oil Pump Stock Pressure Stock Volume M295
Fits Gen III & IV 4.8 5.3 5.7 6.0 6.2 LS1 LS6 LS2 LS3
The Melling M295 pump is a standard pressure, standard volume pump that is considered a suitable replacement for the factory oil pump (GM part # 12586665) and offers improved resistance against cavitation at higher RPMs. The cast aluminum housing is CNC-machined and hardcoat anodized. The cast iron cover is CNC-machined and phosphate coated. The relief valve features a screw-in valve plug. The factory LS oil pump suffers from cavitation above 6,200 RPM, which results in a drop in oil flow of nearly 1 GPM by 7,000 RPM. This cavitation can also aerate the oil, which causes drops in oil pressure and can result in oil starvation. Engines that run at RPM's above 6,200 should use an upgraded Melling pump to prevent these issues.

MELLING M295 LS OIL PUMP GEN III
Easy install and great pump. Did the install with rotating the crank to help align pump and DONT FORGET TO PRIMER (PRE OIL) the pump before starting the motor! This ensures a healthy pump install.
