Delphi FG1173 fuel pump module for the 2010-2015 Toyota Prius 1.8L and 2012-2015 Toyota Prius Plug-In 1.8L sits in the fuel tank, where its electric pump sends gas to the engine and its float arm tracks the fuel level.
A worn fuel pump assembly can show up as hard starting, stalling or a gas gauge that reads wrong. A failed fuel pump relay, a blown fuse, a clogged fuel injector or a damaged wire at the connector can bring on the same trouble, so track down the real cause before you order.
This Delphi fuel pump module is a direct-fit replacement for the 2010-2015 Toyota Prius and the 2012-2015 Toyota Prius Plug-In, both with the L4-1.8L engine. Each car takes one module.

Does the Delphi FG1173 fit both the 2010-2015 Toyota Prius 1.8L and the 2012-2015 Toyota Prius Plug-In 1.8L?
Yes. The Delphi FG1173 is a direct-fit replacement for the 2010-2015 Toyota Prius 1.8L and the 2012-2015 Toyota Prius Plug-In 1.8L.
Does the Delphi fuel pump module assembly come with a float arm and tank seal?
Yes. This module includes its float arm, internal strainer, tank gasket or seal and an instruction sheet; the lock ring, mounting hardware and pressure regulator are not included.
What sender resistance does the Delphi module's float arm have?
The Delphi FG1173 float arm sender reads 408 ohms with the tank empty and 15 ohms with it full, the range the gas gauge uses to show the fuel level.
How can a failing in-tank fuel pump module show up?
Long cranking before a start, the engine dying or an inaccurate gas gauge can mean this in-tank module is failing; a shop can test fuel pressure and the level sender for you.
Should the tank be cleaned before installing the Delphi fuel module?
Yes. Check and clean the fuel tank before fitting this module to avoid unnecessary returns, and follow the instruction sheet in the box for the steps.
