Fuel Level Sensor for Nissan Armada and Titan

Standard Ignition LSF104 is a direct replacement fuel level sensor for select Nissan trucks and SUVs. It is built with a plastic housing, a finger-style sender contact design, and an included float to restore accurate fuel tank level input.

Compatible with 2004 Nissan Pathfinder Armada, 2005-2006 Nissan TITAN, 2007 Nissan Armada, 2007 Nissan TITAN built to 2/07, and 2008 Nissan Armada built to 6/08, this sensor supports OE-style fitment for common fuel gauge concerns. The Standard Ignition LSF104 also cross-references Standard Ignition FLV106 for the same application.

Key Features

• Direct replacement fuel level sensor
• Plastic construction with included float
• Finger-style sender contact design
• Male rectangular plug-in connector
• 3 blade plug terminals with 2-wire harness interface
• Single connector layout for straightforward OE-style connection

Detailed Description

The Standard Ignition LSF104 fuel level sensor is engineered for vehicles that need a replacement sender to restore tank level signal accuracy. Its direct replacement design follows the original connection style with a male rectangular connector, female blade plug terminals, and a 2-wire interface, helping maintain proper communication between the fuel tank sender and the gauge system. The included float and finger-style contact design support consistent fuel level readings in the tank.

This part number, LSF104, is a practical choice for Nissan Armada and Nissan TITAN service work where the fuel gauge reads incorrectly or the sender signal has become unstable. It also fits 2004 Nissan Pathfinder Armada, making it a useful OE-style replacement across multiple Nissan fuel delivery applications.

Common Issues It Can Help Solve

• Fuel gauge reads empty, full, or fluctuates unexpectedly
• Incorrect fuel level display on the instrument cluster
• Sender signal loss from worn internal contacts
• Intermittent tank level readings during driving
• Replacement need after fuel tank service or sender failure

Installation Notes and Tips

Verify the connector style, terminal layout, and vehicle build date before installation. This sensor is not adjustable and does not include a wiring harness or gasket, so confirm the existing tank components are serviceable and match the OE configuration. For best results, compare the original sender assembly to the LSF104 before installation on Nissan Armada or TITAN models.

Quality Assurance

Standard Ignition supplies OE-style replacement electrical and fuel system components for service applications. The LSF104 is built as a direct replacement part for the listed Nissan fitments and is intended to restore proper fuel level sensing performance.
