The fuel sender assembly consists of the following major components:

• The fill limit vent valve (1)
• The fuel feed pipe (2)
• The fuel tank pressure sensor (3)
• The fuel level sensor (4)
• The fuel pump electrical connector (5)

The modular fuel sender assembly mounts to the threaded opening of the plastic fuel tank with a seal and a retainer ring. The reservoir, containing the exterior inlet strainer, the electric fuel pump and the fuel filter, maintains contact with the tank bottom. This design provides:

• Optimum fuel level in the integral fuel reservoir during all fuel tank levels and during driving conditions
• An improved tank fuel level measuring accuracy
• An improved coarse straining and added pump inlet filtering
• More extensive internal fuel pump isolation for noiseless operation
