These were made by Gates Corporation in Colorado specifically for Datsun Parts as a proprietary part. Hey our competitors sell gobs of other Gates hoses so they love how there products are made. Great price too.
67 1/2 - 70 Solex carburetor positive crankcase ventilation hose. These are being supplied now as outer rubber with inner cloth sandwiched and impregnated in between the rubber in the same manner as all of the newer Nissan radiator hoses, heater hoses and aftermarket hoses all sold as well by other vendors. Gee, guess the design is really good then! There is no pressure in this hose, but the rubber used is designated for oil resistance and the inner cloth offers additional strength. Far superior to Nissan original where external cloth webbing became so dry that it would make a crunching sound when squeezed AND LEAK OIL EVERYWHERE. Squeeze yours! Nissan originals don't carry the lifetime warranty.
