Melling Engine Parts Melling is a leading manufacturer of aftermarket oil pumps. We are also a full line distributor of camshafts, timing components, valve train, cylinder sleeves, expansion plugs, and tools for the engine building industry.

A High-Volume Pump will push more oil through the system. It has larger gears to move more oil per revolution. These pumps are good for performance engines with larger bearing clearances. The added oil will help maintain oil pressure and carry away heat.

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.

Larger clearances on serious performance and race engines flow quicker so you need a pump that is capable of pushing more oil volume to keep those larger clearances full. Stock or mild performance engines don't really require that much oil flow because the clearances are much less and therefore "flow" oil much less.
