Product Details

Features

  • Bosch "044"-style pump, 85 GPH free flow, aluminum housing
  • Corvette-style 58 PSI return regulator with built-in filter
  • Includes all fittings and 25' of hose for a complete install
  • Return-style — requires a return line, even for this EFI kit

Description

This kit is a complete fuel delivery solution for LS EFI engine swaps, combining a Bosch "044"-style fuel pump with TSP's Corvette-style fuel filter pressure regulator. The pump delivers an 85 GPH (320 LPH) free flow rate; the regulator maintains 58 PSI.

This is a return-style regulator setup — even though this kit is built for EFI applications, it still requires a return line back to the fuel tank; it is not a returnless design. Mount the regulator as close to the fuel tank as possible for correct 58 PSI operation.

Before ordering, confirm the correct filter inlet/outlet fitting specs with TSP. This listing's Specifications currently list two conflicting sets of filter port sizes and attachment types (-10 AN O-ring female, and separately -8 AN male) — these can't both be accurate for the same ports, and this needs to be resolved before publishing.

The kit includes all necessary fittings and 25' of hose, along with a 5-micron paper filter element and mounting bracket.


Applications
Universal, gasoline EFI applications. Commonly used for GM LS EFI engine swap conversions, street performance applications, and custom fuel-system builds.

Pump Specifications

Q&A

Does this kit still need a return line, even though it's labeled "EFI"?
Yes — this is a return-style fuel pressure regulator, so a return line back to the fuel tank is required. “EFI” refers to its compatibility with EFI fuel-system requirements, not a returnless design.

What size fittings does the filter/regulator use?
The current listing contains conflicting port specifications. Confirm the inlet, outlet, and return port sizes directly with TSP before ordering additional hose, fittings, or adapters.

What flow rate does the pump provide?
The fuel pump is rated at 85 GPH (320 LPH) free flow.

Does this kit include hose and fittings?
Yes — the kit includes the necessary fittings and 25 feet of hose for installation.

What's the maximum pressure this regulator supports?
The regulator is rated for 58 PSI.
