Canton Racing Accusumps are oil reservoirs that connect to the engine's oiling system. They are designed to collect pressurized oil from your engine and store it so that it may be discharged when oil pressure is low. Canton Racing Accusump oil accumulators deliver oil before starting to eliminate dry start scuffing (pre-oiling). They also discharge oil during low oil pressure surges to protect against engine damage during demanding racing conditions. The original 3 Quart Accusump is ideal for V-8 and high horsepower V-6 and 4 cylinders engines. This system has been providing pre-oiling and surge protection in all types of racing and recreational vehicles for over 30 years. Has a 16" long and 4-1/4" dia. body.
