Fuel Pump Cap – Mopar (52014053AB)

Fuel Pump Cap delivers fuel from the tank to the rail at the pressure the calibration expects. Output falls off gradually with wear, so the first symptom is usually a lean code or a misfire under load rather than a no-start.

Replace the Fuel Pump Cap when a lean code appears under load, when the engine cranks without starting, or when rail pressure bleeds down overnight. Change the fuel filter with the pump, because the debris that killed one shortens the life of the other.

Ordering reference for the Fuel Pump Cap is part number 52014053AB, categorised under Fuel Pumps & Senders. Match that number against the component you are removing before you order.

This is MOPAR dealer-sourced stock rather than an equivalent, so the number on the Fuel Pump Cap traces straight back to the manufacturer.
