David Reher of Reher Morrison:
"One of the best investments a sportsman racer can make for a wet-sump engine is an oil accumulator such as an “Accusump.” An oil accumulator is a sealed cylinder that contains a floating piston. Pressurized air on one side of the piston forces a reserve supply of oil into the engine if the flow from the internal oil pump is momentarily interrupted. An accumulator works automatically and requires virtually no maintenance except regular cleaning. Unfortunately, accumulators are seldom seen in drag racing. That’s a pity, because they really work."
