Available to prevent overpressurization and rupture of the pump or hose. This kit is not for use in fuel dispense applications. The kit includes instructions per Fig. 7. For fuel applications, order Model 236267 pump which is equipped with pressure relief valve 112353. For aluminum Husky 1040 pumps. Pressure range: 150 to 180 psi (1.03 to 1.4 MPa, 10.3 to 14 bar). Use Only Genuine GRACO Parts and Accessories. Kit includes instructions. Thermal expansion of fluid in the outlet line can cause overpressurization. This can occur when using long fluid lines exposed to sunlight or ambient heat, or when pumping from a cool to a warm area (for example, from an underground tank). Overpressurization can also occur if the Husky pump is being used to feed fluid to a piston pump, and the intake valve of the piston pump does not close, causing fluid to back up in the outlet line. Install kit between fluid inlet and outlet manifolds.
