Performance Oil Pump Upgrade for Ranger/BT50 P4AT and P5AT

Ford Ranger & Mazda BT-50 P4AT / P5AT Gear-Type Oil Pump Upgrade

The factory oil pump fitted to Ford Ranger and Mazda BT-50 P4AT and P5AT diesel engines uses a vane-style design, which can be prone to pressure inconsistency under high load, towing, or performance conditions. This gear-type oil pump upgrade replaces the original vane pump with a more robust and reliable solution, delivering improved oil pressure control and long-term durability.

This upgrade kit is engineered as a direct replacement for the OE pump and is suitable for both 2.2L P4AT and 3.2L P5AT engines. The gear-driven design provides consistent oil delivery, making it an ideal choice for vehicles used in towing, off-road, fleet, or performance applications.

The kit includes the required hardware and O-ring for installation. During fitment, the original oil pressure pipe from the pump to the cradle is deleted and replaced with the supplied fastener and washer, which is critical for correct oil pressure operation. Assembly lube should be applied to the pump prior to installation to ensure proper priming on first start-up.

In some applications, minor modification to the oil pan baffle may be required to provide clearance for the upgraded pump housing. This can be resolved by either trimming or removing the baffle as outlined in the manufacturer’s installation guidance.

This oil pump upgrade is recommended for anyone seeking increased reliability and peace of mind in Ford Ranger and Mazda BT-50 diesel engines, particularly in harsh operating environments.
