Key Features

• Fuel injection pressure regulator O-ring for fuel rail sealing
• OE-style design for direct replacement service
• Tested and inspected in an ISO 9000-compliant environment
• Built to meet or exceed original equipment specifications
• Designed to address common sealing failures in fuel delivery systems

Detailed Description

Standard Ignition SK93 is an air and fuel delivery sealing component used at the fuel rail and pressure regulator interface on many GM passenger cars and light trucks. It is a practical replacement for service work on applications including the Chevrolet Cavalier, Chevrolet Malibu, Pontiac Grand Am, Oldsmobile Alero, and Buick Regal. This part cross-references 217-439 and 800-9279 for the same application.

As a fuel injection pressure regulator O-ring, SK93 helps restore a proper seal where fuel system leakage, pressure loss, or hard-start concerns can occur after the original seal ages or is disturbed during repair. The design follows OE-level dimensional and performance targets so it can be used in routine fuel system maintenance on compatible GM platforms.

What It Is Used For

• Fuel seepage at the fuel rail or pressure regulator seal
• Fuel odor caused by a deteriorated O-ring
• Pressure loss related to a worn sealing surface
• Service repairs after fuel rail or regulator removal
• Replacement of an aged seal on Chevrolet, Pontiac, Buick, Oldsmobile, and Cadillac applications

Installation Notes and Tips

Clean the sealing surfaces before installation and inspect the fuel rail and regulator for wear, nicks, or contamination. Lubricate the O-ring with clean engine oil or approved fuel-system lubricant during assembly to reduce pinching and help the seal seat correctly. Verify the application by year, make, and model before installation; SK93 is listed for vehicles such as the 1990-2005 Pontiac Grand Prix, 2000-2005 Chevrolet Impala, and 1991-2005 Buick Century.
