Shields Hose 16-337-0380S Silverado 4000 Type B1-15 Outboard Fuel Line 3/8" x 250'

The Shields Silverado 4000 Type B1-15 outboard fuel line is engineered for maximum protection against ethanol-blended fuels in marine applications. This EPA and CARB compliant fuel hose meets stringent emissions standards for modern marine engines.

Key Features:

• Premium THV (thermoplastic fluoropolymer) barrier layer prevents fuel permeation and resists ethanol degradation
• Polyester reinforcement provides superior strength and burst resistance
• Weather and UV-resistant CPE (chlorinated polyethylene) cover protects against harsh marine environments
• Gray exterior color keeps hose cooler in direct sunlight, reducing fuel vapor formation
• 3/8" inside diameter suitable for most outboard and sterndrive applications
• 250-foot bulk spool for custom installations and marine service facilities
• Type B1-15 rating for above-deck and below-deck fuel systems

This professional-grade fuel line is ideal for boat builders, marine mechanics, and DIY boat owners who need a reliable, long-lasting fuel delivery system that meets or exceeds USCG standards for marine fuel hose.
