This is a new very high quality and very correct water pump by-pass hose. This is the small hose that fits on the bib or outlet on the water pump. This is used on the M38, M38A1, and M170. These are very hard to find. This will fit both the 134L and 134F motors. This is US MADE by Dayco and is fabric reinforced on the inside. This is real US quality.
