This is the most commonly used system for turbocharger prestart and shutdown lubrication systems, before installation. Studies have shown that turbocharger lube systems, other than those that are factory-engineered, can be an additional cause of failure. Fittings may loosen, supply lines may break, or secondary pressurization components may fail. A fire apparatus has many demands placed on it.
