  1. Install outlet hose to reservoir ( LS1 with cooler shown, remote-mount reservoir on L36). (Pump mounted on LS1, body mounted on L36)

    2. Important: Inlet and outlet hoses must be oriented so as adequate clearance is maintained between both hoses and surrounding components to prevent chafing. Use minimum clearance of 12 mm (.47 inch). The outlet hose must not be twisted during installation. Do not bend or distort inlet and outlet hoses to make installation easier. Failure to follow these procedures could result in component damage.
