It meets SAE J1527 Type B1-15 and is EPA and CARB compliant, and it is resistant to ethanol-blended fuels, making it a safe choice for modern pump-blend gasoline. Construction uses a THV barrier layer to block fuel permeation, a Nitrile jacket, polyester reinforcement for strength, and a weather- and UV-resistant CPE cover. The gray cover is designed to keep the hose cooler and helps prevent vapor lock in the fuel line. This hose is not fire retardant, so it is intended for above-deck use rather than below-deck engine compartment routing.\u003c\/p\u003e\u003cp\u003eThe Silverado 4000 line is offered in two inside diameters, 5\/16 inch and 3\/8 inch, so it covers the fuel line sizing used across a wide range of outboard fuel systems. Each diameter is available in multiple put-up lengths, from a 10 foot polypac coil for smaller repairs to 25 foot and 50 foot cartons for larger installations, rigging shops, and multi-boat fleets.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sierra\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 16-337\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Outboard fuel line \/ marine fuel hose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Polyester reinforcement, Nitrile jacket, THV barrier layer, CPE cover\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Gray\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard:\u003c\/strong\u003e Meets SAE J1527 Type B1-15\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompliance:\u003c\/strong\u003e EPA and CARB compliant\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuel Compatibility:\u003c\/strong\u003e Resistant to ethanol-blended fuels\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Above-deck primer bulb fuel line applications\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFire Retardant:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAvailable Inside Diameters:\u003c\/strong\u003e 5\/16 inch, 3\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter - 5\/16 Inch Size:\u003c\/strong\u003e 5\/16 inch (7.9 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter - 5\/16 Inch Size:\u003c\/strong\u003e 1\/2 inch (12.75 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter - 3\/8 Inch Size:\u003c\/strong\u003e 3\/8 inch (9.5 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter - 3\/8 Inch Size:\u003c\/strong\u003e 35\/64 inch (13.72 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAvailable Lengths:\u003c\/strong\u003e 10 feet, 25 feet, 50 feet\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSizes \u0026amp; Options\u003c\/h3\u003e\u003cp\u003eFirst pick the inside diameter that matches your boat's existing fuel line or primer bulb fitting, 5\/16 inch or 3\/8 inch.
