Good To Know

Q: Why do carburetor boot insulators crack over time? A: Exposure to fuel vapors, engine heat, and ozone breaks down the rubber, causing micro-cracks that leak air.

Q: Should I use silicone sealant during the installation? A: No, clean mating surfaces and a properly tightened clamp should provide a perfect seal without extra sealants.

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