Design Engineering DEI 10672 Vapor Block 1" ID x 36" Fuel Line Sleeve

The Design Engineering DEI 10672 Vapor Block is a high-performance fuel line sleeve designed to protect fuel lines from radiant heat and prevent vapor lock conditions. This 36-inch sleeve features a 1-inch inner diameter and is engineered to maintain cooler fuel temperatures in high-heat environments.

Key Features:

• 1-inch inner diameter accommodates standard fuel lines
• 36-inch length provides coverage for extended routing applications
• Reflects radiant heat away from fuel lines to prevent vapor lock
• Helps maintain consistent fuel flow and engine performance
• Durable construction withstands harsh under-hood and undercarriage conditions
• Easy slip-on installation over existing fuel lines
• Ideal for automotive, racing, and high-performance applications

Vapor Block sleeves are essential for vehicles operating in extreme heat conditions or with fuel lines routed near exhaust components, headers, or turbochargers. By keeping fuel temperatures lower, this sleeve helps prevent fuel vaporization that can lead to hard starting, hesitation, and performance loss.
