The Walker Products 17191 Fuel Injector Seal Kit offers a reliable solution for restoring proper sealing function between the fuel injector and intake manifold or fuel rail. Over time, injector seals can degrade due to constant heat cycles, chemical exposure, and engine vibration—leading to fuel leakage, vacuum leaks, and poor engine performance. Each Walker Fuel Injector Seal Kit includes OE Replacement O-rings, grommets, insulators, and seals tailored to the specific injector application. These components are manufactured from high-grade rubber and polymer materials engineered to withstand high engine temperatures and long-term fuel exposure, including ethanol-blended fuels. Designed to meet or exceed OE specifications for fit, sealing performance, and durability, these kits ensure a leak-free seal and restore optimal fuel atomization and injector performance. Ideal for preventative maintenance or repair situations, Walker Fuel Injector Seal Kits help eliminate common drivability issues such as hard starting, rough idle, misfires, or reduced fuel efficiency—ensuring consistent engine operation and emissions compliance.
