*Note: Walbro does not warranty this pump for E85 use. If your application requires an E85 certified pump you may want to consider selecting a Stage 2 fuel kit.

** IMPORTANT: Do NOT attempt to run this kit in line with our Stage 2 kit. The Stage 2 kit is a higher flowing kit and this will not only restrict the flow of the stage 2 kit, it will result in failures.
