The modular fuel sender assembly mounts to the threaded opening of the plastic fuel tank with a multi-lipped seal and a threaded retainer (nut). The reservoir, containing the exterior inlet strainer, the electric fuel pump and the pump strainer, 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
• Improved tank fuel level measuring accuracy
• Improved coarse straining and added pump inlet filtering
• More extensive internal fuel pump isolation for noiseless operation
