DPTOOL Universal Pneumatic Diesel Fuel Injector Puller Kit — 28pc, Air Hammer with 20 Adapters & Extensions

DPTOOL's 28-piece universal pneumatic diesel fuel injector puller kit is a complete workshop solution for extracting stubborn diesel injectors using a high-impact air hammer and multiple adapter screws.

This professional-grade kit combines a pneumatic hammer with 20 adapter screws, hooks, extension rods and connectors to tackle a wide range of diesel injector removal jobs. It’s engineered to free injectors that are seized or difficult to remove by hand, reducing labor time and the risk of damage to the injector or cylinder head when used correctly. The kit supports many common injector types from Bosch, Denso, Cummins, Siemens and others, and includes both US and EU fittings for flexible shop air connections.

How does the pneumatic hammer make injector removal easier?

The included pneumatic hammer delivers rapid impacts that vibrate the injector free from carbon buildup, corrosion or seized seals. Its operating range runs at roughly 20–30 impacts per second and produces significant torque to break the injector’s bond without excessive manual force.

• Air-driven hammer: about 1000 NM impact strength
• Operating pressure: 0.6–0.8 bar recommended
• High-frequency vibration helps release stuck injectors safely

Which injector types and vehicles will this kit fit?

The kit is designed as a universal solution that covers the most common diesel injector screw sizes and standards. It includes conversion screws for multiple manufacturers and common sizes so you can match the correct adapter to your injector’s threaded interface.

• Adapters for Bosch 110/120, Denso, Cummins and Siemens
• Thread sizes: M8, M10, M12, M14, M15, M17, M19 variants
• Special adapters: CRIN1, CRIN2, CAT320, XF and BY/CY styles

What parts are included and how do they aid in deep or tight locations?

The set supplies everything needed to reach and pull deeply seated injectors, including two extension rods, a puller hook and a length of air hose with a control valve. These components let technicians adapt the tool to confined engine bays and deeper injector bores without improvising parts.

• 20 conversion screw adapters for broad compatibility
• Two extension rods (11.8" and 5.4") for deeper access
• 31.5" connect tube plus valve and US/EU standard connectors
• Puller hook for recessed injector positions

How should I choose the right adapter and use the kit safely?

Start by measuring the injector’s screw size and selecting the matching conversion adapter; using the wrong adapter can slip or damage threads. Always secure the injector puller assembly and use the valve to control air flow, following standard shop safety procedures and wearing eye and hand protection.

• Measure injector screw before selecting adapter
• Attach correct adapter, hook, and extension for reach
• Set air pressure to recommended 0.6–0.8 bar and test briefly

Who is this for: The DPTOOL 28-piece universal pneumatic diesel injector puller kit is aimed at professional mechanics, diesel technicians and experienced DIYers who work on commercial or passenger diesel engines. It’s ideal when injectors are corroded, carbon-locked or otherwise stubborn, and when a controlled pneumatic impact is preferable to brute force. If you’re unsure about fitment for a particular vehicle, measure the injector screw size first to confirm compatibility with the included conversion screws.
