This is a fuel injector sleeve cup remover and installer for use on 7.3L Ford Powerstroke. This tool is made to be used with cup F4TZ-9F538-A. This tool is made to be used with 7.3L F Superduty 250-550 ford trucks.
The ATC 303-DS105 Ford 7.3L Fuel Injector Sleeve Cup Remover & Installer is a professional-grade diesel engine service tool designed specifically for Ford 7.3 L PowerStroke® engines. This dual-function toolset accurately extracts worn or corroded fuel injector sleeves (injector cups) and installs new sleeves straight and true without damaging the cylinder head bore or injector sealing surfaces — a critical factor on high-pressure diesel engines where precision matters.
Manufactured to work with the OEM sleeve specification F4TZ-9F538-A, this tool eliminates the guesswork and risk of makeshift methods that can lead to costly repair bills or premature failures. The ATC 303-DS105 is engineered from professional-grade steel with precision engagement surfaces that ensure controlled, concentric sleeve removal and installation — improving reliability and reducing labor time for heavy-duty technicians, fleet service operations, and diesel rebuild facilities.
Key Features & Benefits
-
Dual-Function Design: Combines both fuel injector sleeve removal and installation in a single professional tool.
- OEM Fit: Built to fit Ford 7.3L PowerStroke injector sleeves (F4TZ-9F538-A) for proper alignment and seating.
- Precision Engineering: Machined engagement surfaces reduce risk of bore distortion compared to improvised tools.
- Professional-Grade Construction: Heavy-duty steel for repeated use in service bays and shops.
- Efficiency: Saves labor hours by enabling in-place injector sleeve service without cylinder head removal.
- Protects Engine Integrity: Helps avoid costly damage to the cylinder head or fuel system components when servicing injector sleeves.
Applications
-
Designed for Ford F-Series Super Duty 250, 350, 450, and 550 trucks powered by the 1999–2003 7.3 L PowerStroke diesel.
- Ideal for heavy-duty diesel mechanics, fleet maintenance departments, and professional rebuild shops performing injector sleeve replacement.
- Serves both removal of old injector sleeves and installation of new OEM spec sleeves during top-end engine service.
Why It Matters
Injector sleeves are precision sealing components that prevent fuel and combustion gases from leaking into unintended areas. On the Ford 7.3 L PowerStroke — an engine operating under high fuel pressures — improper removal or installation can cause fuel leaks, combustion inefficiencies, and expensive cylinder head damage. The ATC 303-DS105 tool ensures these high-value components are serviced accurately and professionally, reducing return repairs and extending engine life.
