Stuck injectors on a DD15 can turn a routine fuel system repair into an absolute nightmare. The ATC J47391 provides the mechanical, collinear pulling force required to extract seized components safely.

The High Stakes of DD-Series Fuel System Overhauls

Modern Detroit Diesel DD13, DD15, and DD16 engines feature a high-pressure common-rail fuel system where injectors operate under intense thermal stress and tight machining tolerances. Over hundreds of thousands of miles, combustion heat combined with carbon blow-by creates a chemical bond that literally glues the injector body into the cylinder head cup. Attempting to pry or twist a stuck injector free using generic tools will immediately bend the injector body, fracture the fuel feed lines, or mar the precision-ground bore walls. The ATC J47391 is engineered to lock securely onto the injector housing, drawing it straight upward with balanced mechanical leverage that leaves sensitive cylinder head components entirely unharmed.

• Platform-Specific Engagement – Tailor-made specifically for Detroit Diesel Heavy Duty Engine (HDE) platforms including DD13, DD15, and DD16 configurations.
• Collinear Pulling Force – Delivers a perfectly straight, axial pull that prevents the injector from tilting or binding inside the sleeve.
• Cylinder Head Insurance – Eliminates traditional prying methods that result in cracked head castings, damaged sleeves, or gouged bores.
• OEM-Equivalent Blueprint – Form, fit, and mechanical function match the factory OEM J47391 tool profile to standardise workshop efficiency.
• Industrial Strength Construction – A solid 5.00 lbs specialty tool forged out of high-grade, impact-rated structural alloys designed for persistent daily use.

Protect Your Common-Rail Investment

The ATC J47391 Fuel Injector Puller is an indispensable asset for commercial fleet operations, independent diesel repair shops, and heavy-duty field mechanics. Don't risk transforming a straightforward injector replacement into an expensive cylinder head extraction—pull clean with professional hardware.
