Detailed Description

Walker Products 17191 is engineered to replace worn fuel rail O-rings that can harden, shrink, or crack over time. When those seals fail, fuel pressure loss, fuel odor, hard starting, and vapor leaks can follow. This kit is made to restore the sealing integrity needed for consistent injector performance and reliable fuel delivery.

Walker has supplied fuel system components since 1946 and manufactures to meet or exceed OEM standards and specifications. Part number 17191 is a practical choice for injector service, fuel rail repair, and engine refresh work on applications such as Chevrolet Silverado 1500, Chevrolet Tahoe, and GMC Sierra 1500.

Common Issues This Part Addresses

Fuel smell around the engine bay
Fuel seepage at injector or rail connections
Loss of fuel pressure after service or age-related wear
Hard starting caused by leaking seals
Rough fuel delivery from deteriorated O-rings

Installation Notes and Tips

Inspect the fuel rail, injector grooves, and intake manifold sealing surfaces before installation. Clean all mating areas thoroughly and replace damaged or flattened seals during service. Lightly lubricate the new O-rings with clean engine oil or approved fuel-system lubricant before assembly to reduce pinching and improve seating.

Verify correct fitment by year, make, and model before installation. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Quality Assurance

Walker Products is an ISO 9001/IATF16949 certified manufacturer focused on OE-level fuel system components and engine management parts. Part number 17191 is produced to support accurate fitment and dependable sealing performance across the listed Chevrolet, GMC, Buick, Cadillac, Pontiac, Oldsmobile, Isuzu, and related GM applications.
