DHD's high quality high flow CP3 Inlet & Return line fittings are the perfect leak proof solution to plumb your CP3. These fittings are aluminum and come with the washer. You will need to order a AN-8 (Top) and AN-6 (Bottom) to make a complete set.
Note: Picture shows fitting by itself and what both fittings would like like if you were to purchase the other fitting
Reccomendation: DHD recommends these fittings for any install but primarily for those running larger then OE, stroker style pumps with high fuel demand and increased return/flow rates.
