Rolls-Royce & Bentley Fuel Pump — Positive Earth

Does your classic Rolls-Royce or Bentley have a weak or failing fuel pump? Part number UD22715ENP is the correct replacement positive earth SU fuel pump for all pre-1955 Rolls-Royce and Bentley models that retain their original positive earth electrical polarity — covering the Silver Wraith, Silver Dawn, Bentley MkVI and R Type.

Critical — positive earth only: This pump is designed exclusively for positive earth cars. If your car has been converted to negative earth, this pump will not function correctly. Negative earth cars require a different pump. If you are unsure of your car's earth polarity, please call us before ordering.

This is a modern SU-type electronic fuel pump and is fully E10 fuel compliant — an important consideration as E10 fuel becomes increasingly standard at US gas stations. It replaces the original mechanical pump with a reliable, long-life electronic unit.

Signs your fuel pump needs replacing: Engine struggling to start, hesitation or misfiring under load, fuel starvation at higher revs, weak or absent fuel pressure, audible ticking from the pump that is slower than normal, or fuel pump failing to prime when the ignition is switched on.

Fitment — positive earth cars only: Rolls-Royce Silver Wraith — 1946 to 1955, Rolls-Royce Silver Dawn — 1949 to 1955, Bentley MkVI — 1946 to 1952, Bentley R Type — 1952 to 1955.
