Federal-Mogul electrical brushless diesel fuel pump offers enhanced durability and improved fuel economy

Green Car Congress

A typical electric pump is more fuel-efficient than those driven directly by the engine; however, the carbon commutator and brushes found in conventional pumps are subject to wear, which is accelerated by high engine vibration and variations in diesel fuel. Operating durability testing. S15 ULSD: > 10,000 hours.
