Fuel Pump

For a replacement inquiry using Fuel pump OE 311102S200, the old marking is the first comparison point. Vehicle details then help suppliers narrow the relevant fuel pump version. The OE number alone may not separate every version, so compare the connector shape and pin count with the removed pump, then check the operating-pressure specification and fuel-sender arrangement where those details apply, while retaining the available vehicle and VIN details in the quotation request. The supplier RFQ should show OE 311102S200, requested quantity, destination country, and the complete old marking. Include clear comparison photos for the fuel pump.
