Product Overview
Age, vibration, repeated heat cycles, and incorrect clamp placement can crack a hard line or wear it against neighboring parts. This full set renews all six VP44-to-injector tubes for a truck with a confirmed leaking, corroded, or damaged line.
These are VP44 lines, not 2003-up common-rail tubes. Keep every fitting clean and install the line clamps because unsupported tubes can fatigue.

- Six cylinder-specific high-pressure lines
- Connects VP44 pump outlets to all six injectors

Frequently Asked Questions
Q: Are all six injector lines included? A: Yes. The set covers cylinders one through six.
Q: Will these fit a 2003 Cummins? A: No. The 2003-up common-rail system uses different lines.
Q: Why are the clamps important? A: They control vibration that can fatigue and crack the tubes.
Q: Can I feel for a leak with my hand? A: No. High-pressure diesel fuel can penetrate skin; use approved inspection methods.
