Detailed Description

Delphi FG0857 is a fuel pump module assembly engineered for select Hyundai Elantra models from 2011 through 2016. It is an in-tank, standard replacement unit for gas-powered vehicles and includes the fuel pump, fuel level sender assembly, regulator, internal strainer, and seal. The module uses a quick-connect outlet and pin terminals for a factory-style service layout. Delphi FG0857 also cross-references Carter P76715M and Spectra Premium SP3034M for the same application.

Delphi draws on OE experience and supplier knowledge developed over decades of original-equipment work. That background is reflected in the FG0857’s integrated design, which supports fuel delivery, tank level sensing, and pressure regulation in one assembly. This part is a direct replacement choice for Hyundai Elantra fuel system service where the original module has failed or fuel pressure has become unstable.

Common Reasons to Replace

• Hard starting or no-start conditions caused by weak fuel delivery
• Fuel pressure loss or inconsistent pressure at the rail
• Inaccurate fuel gauge readings from a failing sender
• Fuel pump noise, intermittent operation, or electrical failure
• Fuel system contamination affecting pump performance

Installation Notes and Tips
