Description
The 3Z0201037A is a critical component of the dual-pump in-tank system found in modern classic Bentley models. This specific unit serves as the Right Hand Side pump (Item #8 in factory diagrams), responsible for maintaining the high-volume flow required by the Bosch engine management system.
Engineered to replace legacy numbers and align with the newest factory standards (3Z0201037A), this pump is built with upgraded internal gerotors to handle modern ethanol-blended fuels. Whether you are addressing a "Lean Run" fault or a total pump failure, this genuine assembly guarantees the flow rates necessary to protect your twin turbochargers under full boost.
Tech Tip:
The PF116479PA is an in-tank unit. When replacing, the outer rubber sleeve from the old pump must often be cleaned and reused. Critical: Always replace the in-tank fuel filter (PF27288PB) at the same time. If the filter is clogged, the new pump will draw excessive amperage, leading to premature failure of the new 3Z0201037A unit. Always verify the electrical connector pins for signs of "melting" which indicates a high-resistance fault in the wiring harness.
