• 1/8۝ NPT Thread
• Pre Set 35 PSI
• Adjustable 20 ÛÒ 120 PSI
• Includes a 4AN Inline Manifold Adapter
• Easy to Adjust Fuel Pressure Switch
• Safeguards Against Engine Damage
• Automatically Interrupts System Activation If Fuel Pressure Drops

The Nitrous Outlet Fuel Pressure Safety Switch is a low-cost safety component designed to prevent expensive engine damage, caused by fuel pressure loss or fuel pump failure. In the event fuel pressure were to drop below the pressure switch setting, the switch will interrupt signal to the nitrous system relay, preventing the system from activation. These pressure switches utilize a 1/8۝ NPT thread and can be added to the fuel system with the use of an inline adapter manifold or any 1/8۝ NPT tapped hole in the fuel system. These pressure switches come preset at 5 psi for low pressure fuel systems or 35 psi for high pressure fuel systems, however with the turn of a set screw, they are easily adjustable to fit your exact needs.

Note for Australian and European Markets

Unless otherwise stated, this product may be engineered for use in Left-Hand Drive vehicles. Steering components, pedals, shifters, linkages, wing mirrors, instrument clusters, panhard rods/traction bars, drag links, brake boosters, brake or clutch lines, accelerator cables, heater cores, some master cylinders and adjacent parts can vary between LHD and RHD configurations. In some models compenents such as windscreen wiper arms, motors and linkages could differ in their size and orientation. Items such as floor mats & dash mats may have differences in their structure around the front row (or padding in different locations). In many cases items are identical depending on the design of the vehicle and part, but may have differing mounts, lengths or bolt patterns. Carefully review the product images and details to ensure suitability for your vehicle, or contact StreetFX support if you are unsure. Returns are not accepted for special order products.

Important Note Regarding Nitrous & Pressurised Systems

Orders containing nitrous systems or other pressurised canisters may require additional handling and inspection prior to dispatch.

Due to the nature of these products and applicable transport and state regulations, each system is individually inspected, released, and purged where required to ensure compliance with air and road freight standards. While most orders ship within our normal timeframes, this process may occasionally result in slightly longer dispatch times than those advertised.

We do everything we can to minimise delays, and the vast majority of shipments move through without issue. If you are working to a tight deadline or require urgent delivery, please contact us prior to placing your order so we can confirm the most suitable options.

We appreciate your understanding and patience - this process ensures safe, compliant transport and delivery of your order.

Images are supplied by the manufacturer and may be generic. While all efforts are made to provide accurate pictures, there may be differences in the actual product, such as colour, quantity, version, or included components. Please carefully review the description and specifications for details on inclusions or any variations. Some items may be sold individually or in sets, and images may occasionally depict additional products or quantities not included in your purchase. For assistance or clarification, please contact customer support.

Reference Information

Fuel Pressure Safety Switch w/-4 manifold (high pressure)

Nitrous Outlet fuel pressure safety switches are necessary safety devices that can save your nitrous-boosted engine in the event of fuel pump failure. These switches are designed to work in-line with -6AN fuel supply hoses and promptly shut off your nitrous system when the fuel pressure drops below your preset calibration. Specifically engineered to withstand the rigorous demands of running nitrous, the switches are available for high- or low-pressure setups (carbureted, dedicated fuel, or fuel injected systems). Order the Nitrous Outlet fuel pressure safety switch recommended for your specific application.

Features:
• 1/8 NPT inlet on -6 AN manifold
• All switches fully adjustable by set screw at end of pressure switch
• Low-pressure switches shipped preset at 5 psi (adjustable range from 1.5 to 20.0 psi)
• High-pressure switches shipped preset at 35 psi (adjustable range from 20 to 120 psi)
