Product Overview

If diesel is wetting the top of the engine or the return connection cracked during injector work, the small tee may be the whole problem. This brass fitting repairs that connection without buying a complete return-line assembly when the rest of the line is still serviceable.

This fitting belongs to the low-pressure fuel return side. Before ordering, compare the original connection and line size, then inspect the nearby hose and seals so a second leak is not missed.

This is an aftermarket replacement part and is not manufactured or supplied by the original equipment brand.

Key Features & Performance

  • Brass replacement for the original return-line tee
  • Repairs a common leak point on the 6.7L Powerstroke
  • Useful after a cracked fitting or disturbed injector return line
  • Small targeted repair instead of replacing sound surrounding parts

Common Uses

  • Stopping fuel seepage at the injector return tee
  • Repairing a fitting broken during injector or valve-cover work
  • Replacing brittle plastic in an otherwise usable return assembly
  • Correcting air entry or fuel odor traced to this connection

Technical Specifications

  • Product Type: Injector fuel-return tee repair fitting
  • Material: Brass
  • Fuel System Side: Low-pressure return
  • Engine: Ford 6.7L Powerstroke diesel

Installation & Fitment

  • Work only on a cool engine with the ignition off
  • Clean the area before opening the fuel system
  • Confirm the leak is at the tee and not a hose or injector seal
  • Seat each connection fully and check for leaks before road use
  • Keep diesel away from hot surfaces and repair any active leak promptly

Compatibility Notice

Northline Parts does its best to list all known compatible models, but the correct part may fit an application not shown. Model names alone may not guarantee fitment. Compare the original component, reference number, connector or mounting design, dimensions, and any serial-number or production-date break before purchase.

Frequently Asked Questions

Q: Is this the complete injector return line? A: No. This is the brass tee fitting used to repair one connection in the return system.

Q: Can this fix diesel leaking on top of the engine? A: It can when the leak is coming from the original tee. The hose, seals, and nearby connections should also be checked.

Q: Does it fit a 2021 truck? A: This listing is for 2011-2020 applications. Later trucks can use a different return-line connection.
