Injector Feed Tube No.4 for Nissan Diesel ⛽

This high‑pressure fuel line sends precise diesel pulses to cylinder No.4. It keeps rail pressure stable and timing accurate, so the injector can atomize fuel cleanly. Built from seamless steel with corrosion‑resistant coating, its rigid wall and correct internal volume reduce pressure wave bounce and vibration. A correct line here restores smooth idle, stronger torque, and cleaner emissions.

How it works

The tube links the common rail or pump outlet to injector #4. Flared cone ends seal metal‑to‑metal under the union nuts. With every injection event, the line carries up to thousands of PSI without expanding. Proper torque, clean seats, and exact routing (no twist or rub) keep it leak‑free and pulse‑true.

What if it fails ⚠️

Kink, crack, or worn seats cause diesel smell, wet spots, air ingress, hard start, rough idle, cylinder #4 misfire, smoke, rail pressure drop (e.g., low‑pressure DTC),and limp mode. Severe leaks risk engine‑bay fire. Never bend to fit; replace after damage or repeated removals. Always tighten to spec and recheck for seepage.
