DDP 9802CON-MOD Modified Connector Tube Set

Unlock more fuel flow on high-horsepower 24-valve Cummins builds. These are brand-new OEM connector tubes that Dynomite Diesel (DDP) modifies to increase internal volume and remove a common restriction between the injection pump and injectors.

Factory tubes become a bottleneck once you move to larger injectors and a hot-rod VP44 or P-pump conversion. The modified set supports the extra fuel volume needed for 750+ RWHP (typically 800+ recommended) applications. Many owners also notice a more pronounced idle lope on VP44 trucks.

• Set of 6 modified OEM connector tubes
• New high-pressure O-rings

Key features

• Increased fuel delivery volume vs. stock tubes
• Direct-fit replacement — no extra modifications required

These tubes are a targeted upgrade for serious 24-valve Cummins fuel systems that have already outgrown the factory plumbing.
