CNC-Fabricated Stage 1 High-Pressure Oil Pump for 1994–1995 Ford F-Series 7.3L Powerstroke

Description

CNC Fabrication Stage 1 High Pressure Oil Pump (HPOP) – 1994.5–1995 7.3L Powerstroke (Anti-Drainback)

If your early OBS 7.3L is dealing with weak ICP, hard starts, or inconsistent injector performance, the factory HPOP is often the limiting factor. This CNC Fabrication Stage 1 HPOP is a rebuilt, flow-bench-tested upgrade designed specifically for 1994.5–1995 trucks equipped with the anti-drainback pump.

Built to exceed factory specifications, this pump delivers OEM-plus volume and reliability while retaining the correct early-OBS design. It’s an excellent choice for daily drivers, towing rigs, and mild performance builds running up to 205cc hybrid injectors—without the cost or complexity of a full aftermarket race pump.
