DPTOOL Fuel Injector Puller & Teflon Seal Installer — Land Rover & Jaguar 3.0L/5.0L Curved Slide-Hammer

DPTOOL Fuel Injector Puller Remover with Seal Installer is a dedicated slide-hammer kit built to extract and fit injector Teflon seals on Land Rover and Jaguar 3.0L and 5.0L petrol engines without deforming the seals.

Designed for garages and DIY mechanics working on Jaguar X150, XK, X250 (XF), XJ and V8 5.0L Range Rover, Discovery 4 and Range Rover Sport models, this specialist tool set combines a curved slide-hammer puller and a purpose-made seal installer to make injector service faster and safer. The kit matches OEM-equivalent part numbers 310-19, 310-198 and 310-199 and focuses on controlled removal and accurate installation of injector Teflon seals.

How does the slide-hammer puller make removing injectors easier?

The slide-hammer exert controlled impact force that breaks the injector free without hammering surrounding components. Its curved reach helps access injectors in cramped engine bays where straight tools cannot fit.

• Slide-hammer provides repeatable, adjustable pulling force.
• Curved arm designed to reach tight spaces around manifolds.
• Threaded connection secures to injector to avoid slipping.
• Instructions include tightening the end nut to prevent slider off-load.

Can this kit install new injector Teflon seals without damage?

Yes — the installer is shaped to press new Teflon seals on squarely, reducing the risk of rolling or distortion that leads to leaks. It centers the seal and applies even pressure so the seal seats correctly every time.

• Dedicated driver face sized for common Jaguar/Land Rover injector seals.
• Controls pressure to avoid nicking or stretching seals.
• Saves time compared with improvised tools or manual seating.
• Helps maintain OEM-like fit and sealing performance.

Which vehicles and engines are supported by this tool?

This DPTOOL set targets petrol V8 and V6 engines used by Jaguar and Land Rover: specifically 3.0L and 5.0L petrol platforms. It’s intended for common X150, XK, X250 (XF), XJ, Discovery 4, Range Rover and Range Rover Sport models fitted with those injectors.

• Compatible with Land Rover Discovery 4 and new Range Rover models.
• Works on Jaguar X150, XK series, X250 (XF) and XJ where applicable.
• Suited for V8 5.0L and 3.0L petrol injector types.
• Matches OEM-equivalent part numbers 310-19, 310-198, 310-199.

What tips improve success and safety when using the tool?

Minor setup steps make removal smoother and prevent component damage. Properly securing threaded connections and using slight downward pressure on the locking clasp during pulls reduces slippage and ensures cleaner extractions.

• Tighten the nut at the slider’s end before use to avoid detachment.
• Hold slight downward pressure on the locking clasp while sliding the hammer.
• Work gradually with controlled impacts rather than heavy blows.
• Inspect injector and bore after removal before installing new seals.

Who is this for: This tool set is intended for professional mechanics, independent repair shops and experienced DIYers who service Jaguar and Land Rover 3.0L and 5.0L petrol engines. If you routinely remove injectors or need a reliable way to seat Teflon seals without deformation, this DPTOOL kit reduces labor time and lowers the risk of damage compared with improvised methods.
