Description
Product Overview
The Fel-Pro Fuel Injection Plenum Gasket is engineered to replace the original equipment seal on a variety of late‑1990s light‑duty trucks and sport utility vehicles. Crafted from a proprietary fur composite, the gasket offers superior compressibility and resilience, allowing it to conform to the intricate contours of the plenum housing while maintaining a consistent seal under high temperature and pressure conditions. The exterior is precision‑machined from a durable metal alloy, providing a flat, uniform surface that mates perfectly with the engine block and fuel rail components. With dimensions of 12 x 6 x 0.8 inches and a weight of just 2.88 ounces, the gasket is lightweight yet robust, ensuring easy handling during installation. It carries the manufacturer part number MS90269 and is listed under the OEM part number MS90269, guaranteeing exact fitment for the vehicles it supports.
Usage
This gasket is intended for use in the fuel injection system of vehicles produced between 1996 and 2000, including the Isuzu NPR, AM General Hummer, Cadillac Escalade, Chevrolet C1500, Chevrolet C2500, and related models. It is installed during routine maintenance, such as fuel system overhauls, or when a leak is detected in the plenum area. The gasket’s fur material tolerates the cyclic expansion and contraction of the engine bay, reducing the risk of premature failure. Ideal for both professional technicians and experienced DIY enthusiasts, the part simplifies the repair process by eliminating the need for custom fabrication or extensive surface preparation.
