In-Tank 340Lph EFI Fuel Pump

The In-Tank 340Lph EFI Fuel Pump is a high-flow electric fuel pump engineered for modern fuel-injected vehicles requiring reliable, consistent fuel delivery at elevated flow rates. Built by FiTECH Fuel Injection, this pump is purpose-built for automotive enthusiasts upgrading to electronic fuel injection systems, particularly those running FiTech Fuel Command Center installations. Whether you're converting a carbureted engine to EFI or boosting fuel system capacity for performance modifications, this 340-liter-per-hour pump delivers the volume necessary to support fuel-injected engine builds without compromise.

This in-tank design integrates directly into your fuel tank, reducing external plumbing and heat soak associated with external fuel pumps. The pump features a filter sock inlet that protects internal components from sediment and debris, extending service life in older fuel systems or rebuild scenarios. The 5/16-inch hose barb outlet matches common fuel line sizing in EFI applications, allowing straightforward integration with standard fuel rails and distribution blocks. At 340 liters per hour, this pump provides ample margin for multi-port or direct-injection setups, ensuring adequate fuel pressure and volume even under full throttle acceleration or sustained high-RPM operation without voltage drop or flow starvation.

This pump is ideal for street rod builders, classic car enthusiasts, and performance engine builders transitioning from carburetor to fuel injection technology. The compact dimensions (2.7 x 2.45 x 5.65 inches) and lightweight construction (0.89 lbs) ensure easy installation in confined fuel tank spaces without requiring extensive tank modifications. Compatibility with FiTech Fuel Command Center systems makes this the natural choice for complete EFI conversions where fuel system architecture and ECU integration are critical. Proper fuel pressure regulation and inline filtration are recommended to optimize pump longevity and system reliability in high-demand applications.
