Description
Product Overview
The Dorman Fuel Filter Primer Housing Seal Kit is engineered for direct replacement of the original gaskets and screws on select GMC and Chevrolet trucks. Constructed from high‑quality plastic for the housing components and a robust brass bleeder screw, the kit delivers superior durability compared to factory‑issued plastic fasteners. Included are five precision‑molded rubber gaskets, three standard screws, and one brass bleeder screw, all designed to match the OEM part number 12642623. With dimensions of 4.3 x 4.3 x 3.2 inches and a lightweight of 1.51 ounces, the kit fits seamlessly into the vehicle’s fuel system, ensuring a leak‑free seal and optimal fuel flow.
Usage
This seal kit is ideal for professional mechanics and DIY enthusiasts performing fuel system maintenance on medium‑duty trucks. It is suited for both passenger cars and light trucks that require a reliable seal for the fuel filter primer housing. Installation involves removing the old gaskets and screws, then positioning the new rubber gaskets and securing them with the supplied screws and brass bleeder screw. The upgraded brass component reduces the risk of thread failure, extending service intervals.
