*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 inline 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, but it will also result in failures.
