The Silverado 4000 Outboard Fuel Line is resistant to ethanol blended fuels.
This hose is compliant with EPA and CARB regulations.
A THV barrier layer prevents permeation, while polyester reinforcement adds strength and a weather and UV resistant CPE cover is included.
The gray color helps keep the hose cooler and aids in preventing vapor lock.
This hose is intended for above deck primer bulb applications and is not fire retardant.
It meets SAE J1527 Type B1-15.
WARNING - Special care should be taken when coupling Shields series 331, 337 and 368 EPA approved barrier fuel hoses.
Always use a lubricant when inserting a fitting.
Oil based or other lubricants designed for rubber or plastic assembly should be used.
Silicone is not recommended as it may cause coupling retention issues.
Over-sized fittings should not be used.
The fitting should slide into the hose with minimum, but some, resistance.
Using fittings with oversized barbs may result in damage to the barrier layer.
Sierra recommends the use of Oetiker stepless ear clamps or worm drive clamps to attach the fuel hose.
Do not use wire ties or spring tension clamps.
Over-tightening a worm drive clamp may result in damage to the inner layer and cause fuel to get in between the layers.
This will cause the layers to separate and block the flow of fuel.
