Fel-Pro ES73128 is a fuel injector O-ring kit for sealing service on late-model GM engines, built to address worn, cracked, or swollen injector seals that can lead to fuel leaks and poor sealing at the rail or injector bore. Its application-specific design supports Cadillac CTS and Escalade, Chevy Camaro, Corvette, Silverado 1500, Suburban, and Tahoe, plus GMC Sierra 1500 and Yukon applications from the 2014-2020 generation, giving technicians and DIY owners a direct-fit repair option without piecing seals together.

Fel-Pro ES73128 Features:

• Application-specific O-ring design helps match the sealing requirements of the supported GM fuel injector locations.
• Engineered for the fuel injector repair environment, with materials selected to resist swelling and cracking during service.
• Designed to meet or exceed OE specifications and validated for fit, form, and function before installation.
• Supports complete injector sealing service instead of replacing only one compromised seal at a time.
