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 an Accusump 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. This Accusump has a 22" long and 4-1/4" dia. body.
