IMPORTANT:
CYLINDER #2 high-pressure line for the MECHANICAL Cat 3054C/C4.4. Each cylinder has a unique bend — lines are NOT interchangeable between positions. Cat 3054C = Perkins 1104C-44 (equivalent set: 3525A101-A104). Do NOT use on the C4.4 ACERT common rail engine (2008+) which uses 322-3745/333-4733 series lines. If your engine has a fuel rail instead of a rotary injection pump, you have the wrong lines.
Symptoms: fuel weeping at fittings, diesel smell, single-cylinder misfire. Use flare-nut wrenches — open-end wrenches round compression nuts. Bleed fuel system after install.
⚠️ Confirm mechanical (not common rail) engine before ordering.
