Design Engineering Dei 10669 Fuel Line Sleeve ID x Heat Protection - 5/8 36

The Design Engineering DEI 10669 Fuel Line Sleeve provides critical heat protection for fuel lines in high-temperature environments. This 36-inch sleeve features a 5/8-inch inside diameter and is designed to shield fuel lines from radiant heat and abrasion, preventing vapor lock and maintaining consistent fuel flow in demanding automotive, marine, and powersports applications.

Key Features:

• 5/8-inch inside diameter fits standard fuel line sizes
• 36-inch length provides coverage for critical heat zones
• Protects against radiant heat up to 500°F continuous exposure
• Flexible construction allows routing around bends and obstacles
• Helps prevent fuel vapor lock and performance issues
• Abrasion-resistant outer layer protects against chafing
• Easy installation with no special tools required

Ideal for protecting fuel lines near exhaust manifolds, headers, turbochargers, and other high-heat components. The sleeve's flexible design conforms to existing fuel line routing while providing a barrier against heat transfer that can cause fuel vaporization and engine performance problems.
