ReluxGo Diesel Injector Puller Kit - Slide Hammer with M8 M12 M14 Adapters, 7-inch Steel Bar

The ReluxGo Diesel Injector Puller Kit is a slide-hammer removal tool with M8, M12 and M14 adapters designed to extract stuck common-rail diesel injectors quickly and without removing the cylinder head.

This compact kit gives mechanics and DIYers a dedicated way to remove seized Bosch, Lucas and other common-rail injectors using a 7-inch steel bar, a 1.3 lb (.6 kg) slap weight and three threaded adapters stored in a plastic case. Instead of levering or cutting, the slide-hammer transfers controlled impact force down the shaft to free injectors that won’t budge from the nozzle seat. The tool is made from heavy-duty steel so it stands up to repeated use and tight engine bays.

How does the slide-hammer design free a stuck injector?

The slide-hammer concentrates impact energy into a straight pulling force on the injector, minimizing sideways stress on the nozzle and bore. By sliding the weight rapidly toward the handle, the transferred momentum helps break corrosion or carbon sealing the injector without prying on the cylinder head. Use short, controlled strikes until the injector loosens.

• 1.3 lb (.6 kg) slap weight for focused impact
• Steel bar with threaded ends to withstand pulls
• Momentum-based removal avoids leverage damage

Which injector types and thread sizes does this kit work with?

This kit targets common-rail diesel injectors found on many passenger and light-commercial engines, and is especially useful for Bosch and Lucas units. The included M8, M12 and M14 adapters cover the most common stud/thread interfaces so you can attach the puller securely to the injector body.

• M8 adapter for smaller injector fittings
• M12 adapter for mid-size injector threads
• M14 adapter for larger/common diesel injectors

Is the tool easy to use and safe for the engine?

The ReluxGo puller is straightforward: attach the correct adapter, thread into the injector, then slide the hammer weight toward the handle to apply a snap force. Always perform removal on a cold engine and use steady, controlled strikes to avoid damaging the injector bore or surrounding components. The tool is designed to minimize extra disassembly by allowing removal while the cylinder head remains in place.

• Attach adapter, thread into injector securely
• Work with a cold engine to avoid heat-related damage
• Use repeated short strikes rather than excessive force

What does the kit include and how is it stored?

The ReluxGo set includes a 7-inch (178 mm) steel bar, a 1.3 lb (.6 kg) slide-hammer weight and three thread adapters (M8, M12, M14). All components are finished to resist wear and come packed in a compact plastic case for transport and organization. The case keeps adapters and hammer together so you can take the tool to the workshop or job site.

• 7-inch steel rod with two threaded ends
• 1.3 lb slap hammer weight for impact pulling
• M8, M12, M14 adapters in a plastic storage case

Who is this for: The ReluxGo Diesel Injector Puller Kit is intended for professional mechanics, diesel service shops and experienced DIY car owners who need a reliable, compact tool to remove seized common-rail injectors without full cylinder-head disassembly. It’s ideal when dealing with corroded or tightly seated injectors on Bosch, Lucas or similar diesel systems, and for anyone who prioritizes a controlled, repeatable removal method that reduces the risk of collateral engine damage.
