Keep your cabin heater functional. When you upgrade to a Davies Craig Electric Water Pump (EWP®) and remove your belt-driven mechanical pump, you lose the factory heater return point. The DC-8315 adaptor provides a professional, leak-proof solution to reconnect your heater hose.

This alloy adaptor is designed for durability and ease of installation. It allows you to maintain your interior heating while enjoying the benefits of an intelligent electric cooling system. It is a must-have for street cars that require a functional defroster and cabin heat.

NZ Air Filter Expert Advice

If you are running an EWP80 or EWP130 pump, remember that you will also need the #8304 Straight Adaptor to fit this heater return piece. Double-check your hose diameters before cutting your radiator hoses to ensure a perfect, leak-free seal.
