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.

Its alright
Color: Black, Size: 5X-Large
True to size per the size chart. The fabric is soft but it it feels cheap to me. It attracts lint but you can brush it off easily so its not the cheapest material I've dealt with. Also, it is opaque (not see through). There is no front/ back indicator either which is indicative of a cheap shirt in my opinion. Would be friendly for tag sensitive people (to stay positive).

Fuzzballs get wearing once
Color: Black, Size: X-Large
Very smart to wear, but the quality is terrible so after one wash the collar start fraying and fuzzballs start forming. Very disappointing.

Gals can wear this too!
Color: 2 Pack(black+white), Size: XX-Large
Do you know how difficult it is to find a cotton mock turtleneck??? This review is NOT for guys but for gals. Being in menopause my temps are all over the place-- one minute I'm hot then I'm freezing. I needed a short sleeve (plus size) cotton mock turtleneck to wear under a cardigan. I'm so pleased with this shirt... the fabric is soft, NOT see-through, it's breathable since its primarily cotton (95%), it's not super tight, and it's comfortable. Hopefully the info will help other gals looking for similar shirts.
