Nitrous Express 15718 EFI Fuel Pressure Safety Switch with 4AN Manifold

The Nitrous Express 15718 EFI Fuel Pressure Safety Switch with 4AN (D-4) manifold is a critical safety component for nitrous oxide systems. This device automatically interrupts nitrous flow if fuel pressure drops below a user-adjustable threshold, preventing potentially damaging lean conditions that can occur when nitrous is activated without adequate fuel delivery.

Key Features:

• User-adjustable fuel pressure set point for precise tuning to your system requirements
• Automatic nitrous shutoff when fuel pressure falls below the configured threshold
• Includes billet aluminum 4AN (D-4) manifold for clean, inline installation
• Integrates seamlessly with existing -4AN fuel system plumbing
• Protects engine from dangerous lean conditions during nitrous activation
• Professional-grade construction for reliability under high-performance conditions

This safety switch is essential for any EFI-equipped vehicle running nitrous oxide. The included manifold allows for straightforward installation directly into your fuel line using standard -4AN fittings, eliminating the need for additional adapters or custom fabrication. By monitoring fuel pressure in real-time and cutting nitrous delivery when pressure drops, this switch provides peace of mind and engine protection during aggressive nitrous use.
