Keep fuel moving from the tank to the engine with the Delphi Fuel Pump Module Assembly FG1173, an in-tank electric module that draws gasoline from the tank and feeds it to the fuel system. It drops in as a specific-fit replacement for the 2010-2015 Toyota Prius (L4-1.8L) and the 2012-2015 Toyota Prius Plug-In (L4-1.8L), and like every Delphi fuel pump it is built to Delphi's OE standards, then validated and tested to match the vehicle application.
- In-tank electric module: gas-type pump with an internal-strainer inlet and a quick-connect outlet, housed in a plastic body.
- Electrical connection: single female trapezoid connector with four male pin terminals; lower amperage draws less load on the vehicle's electrical system.
- Fuel-level sender: empty float height and float retention match OE specifications for accurate fuel-gauge readings.
- In the box: module assembly with float arm, gasket/seal, and an instruction sheet — no regulator, lock ring, or mounting hardware included.
Signs the original pump may need replacing include long cranking or a no-start, whining from the fuel tank, sputtering under load, and an erratic fuel gauge; diagnose the cause before replacing. Made in Thailand.

Is this an in-tank pump?
Yes. It's an in-tank electric fuel pump module with an internal strainer inlet and a quick-connect outlet, designed for gasoline.
What comes in the box?
The fuel pump module assembly with float arm, a gasket/seal, and an instruction sheet. No fuel-pressure regulator, lock ring, or mounting hardware is included.
Will this correct my inaccurate fuel gauge?
The empty float height and float retention match OE specifications for accurate gauge readings, so if a failed sender in the original module is the cause, this replaces it. Diagnose first.
How is the module wired?
It uses a single female trapezoid connector with four male pin terminals, and its lower amperage draws less load on the vehicle's electrical system.
