Kia 311104Z500 Fuel Pump Assembly

Drain any residual gasoline from the fuel pump/fuel level sensor. Check the strainer for clogging and replace it if necessary. On 2005 and earlier models, the fuel pump can be separated from the filter/sender assembly and replaced, while on later models, the pump is not available individually.

Apply engine oil to the high-pressure pump 0-ring and set the pump on the cylinder head.

Inspect the fuel pump inlet strainer for contamination. If it's dirty, try cleaning the strainer with some clean solvent and an old toothbrush. If the strainer is too dirty to be cleaned while it's installed, remove it from the fuel pump/fuel level sending unit and try cleaning it again. If you still can't clean it adequately, replace it.
