Detailed Product Overview

Standard Ignition SK74 is engineered for fuel injector sealing service on vehicles such as the 2000-2005 Cadillac DeVille, 2000-2004 Cadillac Seville, 2000-2002 Cadillac Eldorado, 2001-2003 Oldsmobile Aurora, and 2004-2005 Pontiac Bonneville. This SK74 fuel injector seal kit uses rubber O-rings in multiple sizes to support proper sealing at the injector and rail pack interface. The design reflects OE-style fit and function for service work where original seals have hardened, cracked, or lost elasticity.

This part cross-references 1G1065 and 12458114 for the same application. Standard Ignition SK74 is a direct service choice when replacing injector seals during fuel system maintenance on Cadillac DeVille, Seville, Eldorado, Pontiac Bonneville, and Oldsmobile Aurora models.

Common Issues This Kit Can Address

• Fuel seepage around injector seals
• Vacuum leaks caused by deteriorated injector O-rings
• Hard starting or rough idle related to sealing loss
• Fuel odor from aged rail pack seals
• Service replacement for cracked or flattened injector seals

Installation Notes and Tips

Inspect the injector body, rail pack surfaces, and sealing grooves before installation. Clean all mating surfaces thoroughly and replace damaged injectors or rails if sealing surfaces are scored or out of specification. Lightly lubricate new rubber seals with clean engine oil or an approved fuel-system lubricant before assembly to help prevent tearing during installation. Confirm the seal sizes and injector style match the vehicle application before reassembly.
