Nitrous Express Electric Fuel Pump

Nitrous Express Electric Fuel Pumps: Purpose-Built for Nitrous Performance

When you're running a nitrous oxide system, fuel delivery isn't an afterthought — it's the foundation of the entire setup. A lean condition under nitrous activation is one of the fastest ways to destroy an engine, which is why Nitrous Express (NX) approaches its electric fuel pumps with the same engineering discipline it applies to every component in its nitrous systems. Founded in 1996, Nitrous Express was built on the philosophy that all horsepower claims must be dyno-proven at the wheel and that every component must be tested before it ever ships to a customer — a standard that carries directly into their fuel pump lineup.

The SAFE System: Standalone Fuel Enrichment Engineered for Nitrous

The flagship of the Nitrous Express electric fuel pump category is the SAFE (Stand Alone Fuel Enrichment) system. Rather than forcing enthusiasts to upgrade or stress their OEM fuel pumps when adding nitrous, NX engineered a self-contained solution. The SAFE system pairs a high-output electric fuel pump with a dedicated composite fuel cell — sized to mount in most factory battery trays without modification — giving the nitrous system its own independent fuel supply. This architecture completely eliminates fuel rail pressure drop in EFI vehicles, one of the most common failure points when running aggressive nitrous tunes.

Nitrous Express offers the SAFE system in multiple configurations to match different application levels:

• Internal High-Output Pump with Adjustable Regulator: Fuel pressure adjusts from 3 to 60 psi with no special jetting required. The boost-referencing regulator makes it compatible with supercharged and turbocharged combinations. When running gasoline, this configuration supports up to 800 nitrous horsepower; on methanol, up to 400 nitrous horsepower.
• External Low-Pressure Pump Version: Delivers 5–12 psi fuel pressure and supports up to 600 nitrous horsepower on gasoline or race fuel, and 300 hp on methanol — an excellent fit for EFI applications where jetting can be matched to lower fuel pressures.
• Compact Standalone Pump (Part #15005): A small-footprint pump designed for motorcycle and powersports nitrous applications, supporting up to 300 hp on gasoline. It features an internal bypass, allowing use without a separate regulator.
• Inline High-Pressure Pump (Part #15078): Rated for up to 700 hp at 5 psi or 500 hp at 45 psi, this inline pump is designed for high-demand applications and must be paired with a bypass-style regulator for proper operation.

Why NX Fuel Pumps Stand Apart

What distinguishes Nitrous Express electric fuel pumps isn't just output numbers — it's the systems thinking behind each product. The SAFE system's integrated fuel level gauge and included mounting hardware make for a straightforward installation. The boost-referencing regulator on high-output versions ensures that as manifold pressure rises in forced-induction applications, fuel pressure rises proportionally, keeping the air-fuel ratio stable under the most aggressive conditions.

This same obsession with precision flows from NX's broader engineering identity. The brand CNC-machines its own valves, jets, and solenoids to eliminate turbulence throughout the nitrous delivery path. Applying that same discipline to fuel pump selection and integration means NX fuel pumps are matched — not just bolted — to the demands of nitrous operation. For any enthusiast running an NX nitrous system, pairing it with an NX electric fuel pump is the logical extension of that system-level approach to performance.
