Moroso offers replacement bypass relief springs for various spur gear oil pumps, used to regulate oil pressure by controlling the flow of oil back into the pump's inlet. The 3-spring kits are designed for use with Nos. 22163, 22164, and other billet Moroso spur gear BBC oil pumps, as well as Tri-Lobe Series external/dry sump pumps. Kits contain a blue (50-60 psi), purple (60-70 psi), and brown (70-80 psi) spring to help tune the engine's oil pressure to a desired level. These springs are a critical component of an oil pump's pressure relief system. When oil pressure exceeds a certain threshold, the spring compresses, allowing excess oil to bypass the main circulation and return to the pump's suction side, which prevents excessive pressure and potential engine damage.
