EFI In-Tank Retrofit Fuel Pump – 340 LPH – Return Style – Professional Overview
The EFI In-Tank Retrofit Fuel Pump – 340 LPH – Return Style is an in-tank retrofit fuel delivery solution designed to work with an existing fuel tank.
Instead of requiring the replacement of the original tank with a dedicated EFI conversion tank or the use of a fuel cell, the retrofit module is designed to install directly into an existing tank. This makes it particularly relevant for engine-swap projects where the original vehicle was equipped with a carbureted fuel system.
The supplied product information identifies the module as a 340 LPH / 90 GPH fuel pump system with a maximum pressure rating of 100 psi.
Its adjustable installation depth is one of its key design features. The module is designed for fuel tanks ranging from 7.00 to 20.00 inches deep, allowing it to accommodate a broad range of tank configurations.
The module also uses AN flare connections rather than NPT threads. The outlet uses an 8AN flare, while the return connection uses a 6AN flare.
Compatibility and Applications
The 340 LPH EFI in-tank retrofit fuel pump is designed for both high-horsepower EFI and carbureted engines, provided the fuel system is configured with the required return-style regulator.
The supplied information specifically identifies the module as suitable for muscle car and truck applications where an originally carbureted engine is being upgraded to an EFI powerplant such as a BluePrint LS or Gen III Hemi.
The module is designed for tanks with an installation depth between 7.00 and 20.00 inches. This depth range should be checked against the vehicle’s existing fuel tank before ordering.
The fuel system must also use a return-style regulator. The supplied product information lists BPP13101BK and BPP13109BK for EFI applications and BPP13206BK for carbureted applications.
This requirement is important because the module is specifically configured as a return-style fuel system.
The pump’s stated support levels vary according to fuel type and whether the application is EFI or carbureted. The supplied specifications state support for up to 780 HP EFI on pump or race gas, 600 HP EFI on E85, 850 HP carbureted on pump or race gas, and 680 HP carbureted on E85.
These figures should be considered application-specific product ratings based on the supplied information rather than universal engine-performance guarantees.
Construction and Fuel System Design
The EFI In-Tank Retrofit Fuel Pump – 340 LPH – Return Style incorporates several design features intended to simplify installation into an existing fuel tank.
The module uses AN fittings instead of NPT threads. The outlet is equipped with a male-thread connection and an 8AN flare, while the return side uses a male-thread connection with a 6AN flare.
The design also incorporates swivel banjo-style AN fittings. According to the supplied description, these fittings reduce the overall protrusion height from the tank and provide additional tank-to-body clearance.
The installation-depth range extends from 7 to 20 inches, providing flexibility when adapting the module to different fuel tank dimensions.
The system provides a 340 LPH / 90 GPH free-flow rate and a maximum pressure rating of 100 psi.
The supplied specifications identify the unit as a kit, with one outlet and one return connection.
For the fuel system to operate as specified, the module must be paired with a compatible return-style regulator. The supplied description specifically identifies regulator options for EFI and carbureted applications.
Why This Fuel Pump Stands Out
The 340 LPH return-style fuel pump is designed around a common challenge in engine-swap projects: upgrading fuel delivery without necessarily replacing the existing fuel tank.
For muscle car and truck applications originally equipped with carbureted engines, the retrofit approach can provide a way to adapt the existing tank to a modern EFI fuel system.
Its 7–20 inch installation-depth range provides flexibility across different tank configurations, while the AN connections offer a defined connection format for the outlet and return sides.
The swivel banjo-style fittings are another practical design feature. By reducing overall protrusion from the tank, they are intended to provide greater clearance between the fuel tank and vehicle body.
The module also supports both EFI and carbureted applications when paired with the appropriate return-style regulator.
Its stated fuel-system support varies by application and fuel type, reaching up to 780 HP for EFI on pump or race gas and 850 HP for carbureted applications on pump or race gas, according to the supplied product specifications.
Who This Product Is Best For
This 340 LPH in-tank retrofit fuel pump is suited to buyers working on engine swaps, muscle cars, trucks, and high-performance fuel-system upgrades.
It is particularly relevant for customers who have an existing fuel tank and want to adapt it for a modern EFI engine without purchasing a dedicated EFI conversion tank or converting the vehicle to a fuel cell.
The product can also be used with specified carbureted applications, provided the fuel system uses the required return-style regulator.
It may be relevant to vehicle owners, engine-swap builders, performance enthusiasts, automotive technicians, restoration specialists, and professional engine-builders working with compatible fuel tanks and fuel-system configurations.
Before ordering, buyers should verify the tank depth, intended fuel type, application type, and required regulator.
