For over 25 years the simplicity and effectiveness of the Accusump has made it the accepted method for providing more continuous oiling and adding longevity to road race and drag race engines.

Today supplying oil pressure to the engine before startup for the purpose of pre-lubricating engine components has elevated the Accusump to use on just about any engine or vehicle

The Accusump, renowned as the pioneering automotive oil accumulator, takes the form of a cylinder-shaped storage container, functioning as a reservoir for pressurized oil. This innovative device plays a crucial role by holding pressurized oil, releasing it precisely during instances of engine oil pressure drop. Interconnected to the pressure side of the engine's oiling system, the Accusump is charged by the engine's own oil pump. Its streamlined and effective design incorporates a hydraulic piston, effectively separating the oil reservoir side from an air-charged side. The oil side integrates an outlet plumbed into the engine's oiling system, controlled by a valve, while the air side is equipped with a pressure gauge (excluding turbo oiler models) and a schrader air valve. The inclusion of the schrader valve allows users to add a pre-charge of air pressure to optimize the Accusump's performance

Accusumps Oil Accumulators serve the purpose of collecting pressurized oil from the engine and storing it for controlled discharge. Upon engine shutdown, when the Accusump valve closes, any retained oil pressure within the Accusump is securely held. During engine start-up, with the opening of the valve on the oil side, the pressurized oil is released into the engine, facilitating pre-lubrication before start-up. Once the engine is running, the oil pump takes charge, pumping oil back into the Accusump. This action moves the piston, pressurizing the Accusump until equilibrium is achieved with the engine's oil pressure. While driving, if the engine's oil pressure experiences interruptions, the Accusump releases its oil reserve, ensuring continuous engine lubrication until the oil pressure returns to normal. The duration of this oil release ranges from 15 to 60 seconds, contingent on the engine's size and speed. In demanding conditions such as racing or vigorous driving, the Accusump automatically fills and discharges as needed during cornering, acceleration, and braking maneuvers.

The valve plays a crucial role in regulating oil flow between the engine and the Accusump. While Turbo-Oilers don't necessitate a valve for oil discharge restriction, as they release all oil during shutdown, Accusump Oil Accumulators require a valve to close off the unit post-shutdown, retaining oil pressure for pre-lubrication upon the subsequent startup.

In intense racing scenarios, a manual valve offers simplicity, mountable on the Accusump or along the feed line for easy access. The operator manually opens the valve before starting the engine and closes it before shutdown.

For enhanced convenience or challenging manual access, a standard electric valve proves ideal. Suitable for daily drivers, boats, or RVs, this valve slowly refills after oil discharge and can be controlled by a remote dash-mounted switch or wired directly into the ignition for automatic opening and closing with ignition activation.

In high-performance applications demanding swift refill and constant discharges, the E.P.C. (electric pressure control) electric valves are recommended. The pressure control system keeps the valve off during normal oil pressure, enabling quick Accusump recharge after discharge. The EPC valve, wired to a remote dash-mounted switch or directly into the ignition, opens and releases stored oil when the engine's oil pressure falls below the preset level.

The ideal operating engine temperature is dependent on the type, size, capacity, workload and environment the engine is working in, however the best engine temperature is usually between 85-105°C or 185°F-221°F
