Fuel Injector Insulator Seal for Kawasaki

This fuel injector insulator seal is a replacement sealing component that sits at the injector base to prevent vacuum leaks and fuel seepage on the Kawasaki Ultra 250X 1500 jet ski.

Overview

This fuel injector insulator seal is a replacement sealing component for the Kawasaki Ultra 250X 1500, positioned at the injector base to keep the intake tract sealed under boost and heat. A sound insulator seal on the Kawasaki helps maintain correct air and fuel delivery, idle quality, and throttle response. It suits riders servicing injectors or chasing vacuum leaks on their personal watercraft.

Good To Know

Q: How many insulator seals do I need? A: Each injector position uses one insulator seal, so order the quantity that matches the number of injectors you are servicing.

Q: Should I replace these when servicing injectors? A: It is good practice to fit fresh insulator seals whenever injectors are removed, since old rubber can harden and leak air.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
