Hello I will answer your question,

 

This is for a 1500 with single tank if yours is different let me know and I will provide the procedure. You will have to drop the tank for this one:

 

Fuel Sender Assembly Replacement

Tool Required

  • J44402 Fuel Tank Sending Unit Wrench.

Removal Procedure

  1. Remove the fuel tank.
  2. Remove fuel lines from sender assembly.

  1. Remove the fuel sender assembly retaining ring using the J 44402.
  2. Remove the fuel sender assembly and the seal. Discard the seal. Caution: Drain the fuel from the fuel sender assembly into an approved container in order to reduce the risk of fire and personal injury. Never store the fuel in an open container.
  3. Clean the fuel sender sealing surfaces.

Installation Procedure



Caution: Drain the fuel from the fuel sender assembly into an approved container in order to reduce the risk of fire and personal injury. Never store the fuel in an open container.

  1. Install the new seal on the fuel tank. Important: The fuel pump strainer must be in a horizontal position when the fuel sender is installed in the tank. When installing the fuel sender assembly, assure that the fuel pump strainer does not block full travel of the float arm.
  2. Install the fuel sender assembly into the fuel tank. Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
  3. Install the fuel sender assembly retaining ring using the J 44402.
  4. Install fuel lines to sender assembly..
  5. Install the fuel tank.
