Detailed Description

This fuel injector seal kit is intended for rail pack fuel injector service on vehicles such as the Buick Century, Chevrolet Camaro, and Pontiac Grand Prix. The seal set includes multiple O-ring dimensions to match common injector rail and body sealing points, helping maintain fuel pressure and reduce leakage at worn seals. If you are servicing a Buick LeSabre, Chevrolet Lumina, or Oldsmobile Cutlass Supreme, SK84 provides the sealing components needed for a proper repair.

Standard Ignition SK84 is part of a service-focused lineup built around OE-style fit and function. The part number SK84 is used across many GM applications from 1984 through 2000, making it a practical choice for injector seal replacement during intake or fuel rail work.

What It Helps Fix

• Fuel odor caused by leaking injector seals
• Hard starting related to fuel pressure loss
• Visible seepage around injector rail connections
• Rough idle from air or fuel leaks at the injector seal
• Seal deterioration found during fuel injector service

Installation Notes and Tips

• Confirm the vehicle uses a rail pack fuel injector seal application before ordering.
• Inspect injector bodies, fuel rail surfaces, and intake sealing areas for wear or damage before installation.
• Clean all mating surfaces thoroughly so the new rubber seals seat evenly.
• Use proper fuel-system service procedures and verify there are no leaks after reassembly.
• For fitment searches, this kit is commonly used on 1984-2000 Buick LeSabre, 1985-1999 Chevrolet Camaro, and 1988-1999 Pontiac Grand Prix applications.
