The 3 Quart High Pressure Accusump is ideal for big cubic inch engines, those that operate with high oil pressures, and for severe racing conditions. If there is room for a unit of this size, the longer length allows it to hold more air and oil. This offers more pre-oiling and surge protection in a narrower oil pressure range. Has a 22 in. long and 4-1/4 in. dia. body. Blue anodized aluminum. Made in the U.S.A.
