RULLINE Injector Seal Installer Kit for Ford GM Subaru — 34720 Teflon Seal Pilot, Installer & Sizer

The RULLINE 34720 Injector Seal Installer Kit is a complete tool set that lets you remove, size, and install Teflon injector seals for many Ford, GM, and Subaru engines quickly and accurately.

When you need to replace worn or leaking injector seals, this kit gives technicians and knowledgeable DIYers the right tools to fit single- and double-sealed injectors from major OE manufacturers. It supports common Hitachi, Bosch, Continental and Delphi injector styles and includes pilot, installer, and sizing tools so seals start easily, seat correctly, and compress to the proper outer diameter before being inserted into the cylinder head.

Which injector types and car makes does this kit work with?

This kit is designed for a broad range of single- and double-sealed injectors used by Ford, GM and Subaru, and it accommodates many Hitachi, Bosch, Continental and Delphi patterns. Compatibility covers numerous GM engines from 2010+ and several Ford and Subaru direct-injection applications.

• Fits Hitachi, Bosch, Continental, Delphi injector styles
• Compatible with many Ford ECO and direct-injection units
• Works with GM engines like 1.4L–6.2L models (2010 onward)
• Applicable to select Subaru injectors and other OE-type units

How does the kit make installation easier and more reliable?

The set includes a pilot cone to guide the seal onto the injector tip, an installer tool to push the seal into place, and a sizer to compress the seal to the correct outer diameter. Those three functions reduce seal twists, improper seating, and head damage during installation.

• Pilot cone starts the seal straight on the injector tip
• Installer pushes the seal evenly into place without deforming it
• Sizer ensures compression to the exact outer diameter for a secure fit
• Reduces risk of leaks and repeated work after install

What vehicle systems or jobs is this kit intended for?

Use this kit whenever you're replacing injector Teflon seals, performing fuel rail service, or diagnosing injector-related leaks. It’s suitable for maintenance, overhaul, and preventive service where injector seals are removed and reinstalled.

• Injector seal replacement and reinstallation
• Fuel-rail or injector servicing and diagnostics
• Engine rebuilds or head work that require re-sealing injectors
• Quick repairs to stop fuel or vacuum leaks at the injector interface

What tools and outcomes should I expect using the RULLINE 34720 kit?

Expect a straightforward, repeatable process: start the seal with the pilot, seat it with the installer, and verify compression with the sizer. The result should be a properly seated seal that fits to spec and reduces service time compared with improvised methods.

• Simple three-step procedure: pilot → installer → sizer
• More accurate seating than manual thumb-pressure installs
• Helps prevent injector misalignment and head damage
• Saves time on garages and home projects

Who is this for: The RULLINE 34720 Injector Seal Installer Kit is intended for professional mechanics, independent shops, and experienced DIYers who service Ford, GM, and Subaru engines and need a reliable way to replace Teflon injector seals.
