The RH350-1017-101 Replacement Heater Line Kit provides insulated, stainless steel pipes that are direct replacements for the aluminum OEM parts. The kit comes with the pipes, adapters and all clamps and fasteners required to complete the installation. The kit interfaces with the existing control valve and P2 hose from the engine. The pipes come equipped with the added reliability of FLARED AN818 COUPLING NUTS instead of less robust compression fittings. The RAMM kit is certified to be replaced "ON CONDITION".
