    Abstract: An oil filtration system including an oil reservoir and a first conduit assembly having a first end and a second end. The first conduit assembly being in fluid communication with the oil reservoir at the first end, and an HEUI pump at the second end. The first conduit assembly includes a first pump coupled to the first conduit assembly, and disposed downstream of the oil reservoir. The first pump adapted to pump oil from the oil reservoir to the first conduit assembly. A primary filter coupled to the first conduit assembly, and disposed downstream of the first pump. A bypass conduit disposed in parallel configuration with the primary filter, and adapted to provide a bypass path for flow of oil therethrough, thereby preventing flow of oil through the primary filter. A secondary filter coupled downstream to both the first conduit assembly and the bypass conduit, and disposed upstream of HEUI pump.
