Vulcan Performance DF02 Adjustable Fuel Plate – 5.9L Cummins (P7100)

Unlock more power and control from your 1994–1998 Dodge Ram 5.9L 12-valve Cummins with the Vulcan Performance DF02 Adjustable Fuel Plate. This precision-machined upgrade replaces the stock fuel plate inside the Bosch P7100 injection pump’s AFC housing, giving you mechanical adjustability over fuel delivery.

Slide the plate to change rack travel and fuel volume. In a stock or mildly modified truck you can pick up useful extra power and better throttle response; with supporting mods (injectors, turbo, exhaust, etc.) many users see 25–140+ additional rear-wheel horsepower depending on setup and how far the plate is advanced.

Key features

• Adjustable design for custom fueling (mild daily/towing to more aggressive performance)
• Direct-fit replacement for the factory fuel plate
• Durable construction built for the Cummins P7100
• Mechanical solution — no electronics or tuning software required
• Proven style of upgrade used across 12-valve Cummins performance builds

Fitment 1994–1998 Dodge Ram 2500/3500 with 5.9L 12-valve Cummins and Bosch P7100 injection pump.

Notes Installation requires removing the AFC housing. Professional installation is recommended. Maximum gains require supporting modifications. The included or typical kit-style AFC spring (when provided) is generally intended for higher-output injector setups. This is a performance part; check local emissions and street-use regulations.

A straightforward, time-tested way to add fuel and adjustability to a 12-valve Cummins without electronics.
