Product Overview

Premium fuel line designed for a life of exposure

Silverado 4000 is ideal for outboard engines where fuel lines are run above deck and exposed to extreme conditions. This polyester reinforced hose features a THV barrier layer that almost eliminates permeation. The CPE weather and UV resistant cover protects the hose from the elements while maintaining its flexibility. The grey cover not only offers a unique look, it helps to reduce heat absorption that can lead to vapor lock. Silverado 4000 meets current EPA and CARB standards and works well in conjunction with above deck primer bulbs.
