NOTES

• The sleeve is designed for 39mm diameter (or DCSS 39/50) pump bodies. For pumps not listed as compatible, measure the outside diameter to ensure it is correct before ordering. If the pump is greater or less than 39mm, this sleeve may not work.
• Installation requires a filter sock. If your pump does not come with a filter sock, you can find compatible fuel pump filter socks, click HERE.
  
• The Walbro F90000262/273 pump has the same connectors as the OEM BMW pump
• Aftermarket pumps can potentially draw more current than what the BMW wiring was designed for. Fortunately, the factory 15A fuel pump fuse provides a safety net. It is a tell-tale to upgrade the corresponding wiring if this fuse ever blows.
