DeatschWerks 265 LPH In-Tank Fuel Pump – 2010+ Subaru Legacy GT / 2003-2008 Infiniti G35 / Nissan 350Z

Feed your modified engine the fuel it demands with the DeatschWerks 265 LPH In-Tank Fuel Pump. This complete setup kit is engineered for the 2010+ Subaru Legacy GT, 2003–2008 Infiniti G35, and 2003–2008 Nissan 350Z — delivering significantly more fuel flow than the factory pump to support bolt-on modifications, forced induction upgrades, and higher power targets. DeatschWerks’ drop-in fitment design means no cutting, no fabrication, and no guesswork — just a clean, reliable fuel system upgrade.

Key Features:

• 265 LPH flow rate — significantly higher than OEM for modified engine applications
• Drop-in fitment — uses factory fuel pump hanger and wiring for a clean, plug-and-play installation
• Complete setup kit — includes pump, installation hardware, and all components needed for installation
• Application-specific — engineered for the 2010+ Subaru Legacy GT, 2003–2008 Infiniti G35, and 2003–2008 Nissan 350Z
• DeatschWerks quality — designed, manufactured, and quality-checked in Oklahoma City, OK
• Compatible with E85 and ethanol blends — DW pumps are built for alternative fuel compatibility

Performance Benefits:

• 265 LPH Flow Rate: Supports power levels well beyond what the factory pump can sustain — essential for turbocharged, supercharged, or heavily modified naturally aspirated builds
• Consistent Fuel Pressure: Higher flow capacity means the pump is never working at its limit, maintaining stable fuel pressure under hard acceleration and high-demand conditions
• Drop-In Simplicity: No fuel tank removal or hanger modification required — installs using the factory pump hanger for a clean, OEM-quality result
• E85 Compatible: Handles ethanol-blended fuels that degrade lesser pump internals over time
• Eliminates Fuel Starvation: Prevents the lean conditions and power loss caused by an undersized factory pump struggling to keep up with modified fuel demands

When Do You Need a Fuel Pump Upgrade?

The factory fuel pump is sized for the stock engine’s fuel demands. As soon as you start adding power — through a tune, intake, exhaust, or forced induction — the engine’s fuel requirements increase. A pump that can’t keep up causes fuel pressure drop under hard acceleration, leading to lean conditions that can damage pistons, valves, and catalytic converters. The DeatschWerks 265 LPH pump provides the headroom needed to support modified builds safely, with enough flow capacity to handle significant power increases without becoming the limiting factor in your fuel system.

Why DeatschWerks?

DeatschWerks has been engineering high-performance fuel system components since 2004, starting with high-flow injectors before expanding into pumps, fuel rails, regulators, and complete fuel system solutions. Every DW product is designed, manufactured, and quality-checked at their Oklahoma City facility — giving them direct control over the engineering and production quality that performance builds depend on. Their drop-in fitment philosophy means you get professional-grade fuel system performance without the complexity of a custom installation.

Perfect For:

• 2010+ Subaru Legacy GT owners running a tune, upgraded turbo, or E85 conversion
• 2003–2008 Infiniti G35 builds with bolt-on modifications or forced induction
• 2003–2008 Nissan 350Z builds requiring more fuel flow than the factory pump can provide
• Any of the above platforms running E85 or ethanol blends
• Builds experiencing fuel pressure drop or lean conditions under hard acceleration

Pro Tip: Upgrade your fuel filter at the same time as the pump. A clogged or restrictive filter will limit the flow of even the best pump and shorten its service life.

Note: Always depressurize the fuel system and work in a well-ventilated area before beginning fuel pump installation. Fuel system work carries fire risk — take appropriate safety precautions.
