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

  • Proven Performance – Tested for over 6 years on injectors ranging from 160/100 up to 450/400 single shots

💪 Construction & Components:

  • Mandrel-bent 304 stainless steel fuel lines

  • Double-flared ends for a secure, leak-free seal

  • All required fittings included — no OEM fittings reused

  • Engineered for durability, flow, and long-term reliability

⚙️ Fuel System Notes:

  • If running injectors larger than 180cc, upgrading the fuel pump or adding an additional stock pump is recommended

  • CNC Fabrication’s Fuel Bowl Delete option is available separately for those wanting a cleaner engine valley and improved access to HPOP components

  • Customer is responsible for supplying 1/2" fuel-rated hose from the pump to the manifold block

📎 Fitment:

  • 1999–2003 Ford F-250 / F-350

  • 7.3L Powerstroke

  • T4 turbo applications

🔧 Installation:

  • Complete kit includes fittings for a full install

  • [Install Instructions Available Here]

This is a battle-tested fuel delivery upgrade trusted on high-horsepower street, tow, and competition trucks—built to feed even the largest injectors with confidence.
