Designed with efficiency in mind, our water pump cover converts the dual outlet cast aluminum cover to a single outlet. Designed to be used in engine swap applications. Hose diameter is stock ATV and 7/8” ID with a ridged bubble at the end to prevent hose blow off under high pressure racing applications. Covers come anodized black with the bolts needed for installation. Factory dowel pins will have to be used. Contact us if you need replacement dowel pins because of seizure in the original cover.
