Product Introduction

INLET & MOUNTING DIMENSIONS 

When installing units that contain a high alcohol product (e.g. E100). Confirm that the plumbing is designed to handle an alternative fuel. For multi-
hose units, piping must align with the footprint. 

Alternative fuels, such as E25, E85, and other ethanol blends, may require special piping materials or components. Consult the piping manufacturer 
to determine if the piping material, fittings, and connectors are compatible with the alcohol-blended fluid being used.
