RULLINE 34720 Injector Seal Installer Kit – 8-Piece, Ford GM & Subaru Engine Compatibility | Precise Seal Installation

Overview

The RULLINE 34720 Injector Seal Installer Kit is a thoughtfully designed 8‑piece set built to support reliable seal seating across a broad range of fuel injector types. This kit targets common single and double sealed injectors from brands such as Hitachi, Bosch, Continental, and Delphi, and it aligns with Ford, GM, and Subaru engine families. By focusing on precise handling of injector seals, it helps create a solid foundation for injector performance without making guarantees about engine outcomes.

In practical terms, this kit is a versatile tool for professional technicians and ambitious DIYers alike. It’s crafted to accommodate the realities of modern engines where injectors and seals vary in diameter and design. The result is a set of tools designed to fit into tight spaces and guide components accurately from start to finish.

Key benefits

• Comprehensive compatibility: Works with a wide range of Ford, GM, and Subaru injector assemblies, including common Hitachi, Bosch, Continental, and Delphi units.
• Versatile applications: Suitable for replacing Teflon seals on multiple injector types, including direct injection variants used in various Ford, GM, and Subaru engines.
• Effortless installation: A pilot cone helps start the seal, while the installer tool pushes the seal into place on the injector tip for controlled alignment.
• Precise compression: The sizer tool ensures the seal is compressed to the correct outer diameter for secure seating in the cylinder head.
• Wide engine coverage: Compatible with GM engines from 2010 onwards, covering models with 1.4L, 1.5L, 2.0L, 2.4L, 2.5L, 3.0L, 3.6L, 4.3L, 5.3L, and 6.2L, as well as select Ford and Subaru engines.

What’s included and how it helps

• 8-piece kit designed for streamline seal installation and controlled compression.
• Pilot cone aids easy starting of the seal, reducing misalignment risks.
• Installer tool guides the seal smoothly into position on the injector tip.
• Sizer tool ensures the correct outer diameter for a secure fit in the cylinder head.
• Engine coverage supports a broad array of Ford, GM, and Subaru applications for diagnostic and maintenance work.

Designed to support careful hand‑work and reliable results, the 34720 kit offers a practical option for projects where seal seating accuracy matters. While results can vary by vehicle and injector type, users may experience easier assembly and reduced rework when the components align with the included guidance and tools.
