Delphi PN4085 Fuel Sending Unit

The Delphi PN4085 is a direct-fit fuel sending unit engineered to OE specifications, delivering accurate fuel level readings to your dashboard gauge. Delphi is a trusted OEM supplier with decades of experience in fuel system components, and this sending unit is built to match the fit, form, and function of the original equipment it replaces.

The fuel sending unit works by measuring the fuel level in the tank via a float-and-resistor mechanism, transmitting a precise resistance signal to the fuel gauge. A faulty or worn sending unit can cause erratic, inaccurate, or unresponsive gauge readings — this Delphi replacement restores proper operation and eliminates guesswork at the pump.

Key Features:

• Manufactured to OE specifications for accurate fuel level measurement
• Direct-fit replacement — no modifications required
• Constructed from corrosion-resistant materials for long-term durability in fuel environments
• Consistent resistance output for stable, reliable gauge readings
• Meets or exceeds original equipment performance standards
• Sourced from Delphi, a leading OEM-level fuel system manufacturer

The Delphi PN4085 is an ideal solution for restoring accurate fuel level indication, whether addressing a faulty float, corroded sender, or failed resistor track. As a dedicated sending unit (not a complete fuel pump module), it is designed for targeted replacement without requiring full module assembly removal on applicable vehicles.
