CNC Fabrication T4 Turbo 4-Line Feed Fuel Bowl Retain Kit – 1999–2003 7.3L Powerstroke
Upgrade your fuel delivery system and eliminate known factory shortcomings with the CNC Fabrication 4-Line Feed Fuel Bowl Retain Kit. Designed specifically for 1999–2003 7.3L Powerstroke trucks running a T4 turbo, this kit addresses fuel starvation and the infamous #8 injector knock that occurs under high RPM and heavy load conditions.
By converting the factory single-feed design into a true 4-line feed system, fuel is delivered evenly to both heads, ensuring consistent pressure to all injectors—especially cylinders #1 and #8 where issues commonly arise.
🔥 Key Features:
-
4-Line Fuel Feed Design – Eliminates fuel starvation and uneven distribution at high RPM
-
Injector Protection – Helps prevent #8 injector knock under load or towing
-
High-Flow Plumbing – Removes restrictive factory Vibralok fittings and failure-prone O-rings
-
Fuel Bowl Retained – Maintains factory fuel bowl while dramatically improving delivery

Mandrel-bent 304 stainless steel fuel lines
