Installation Notes and Tips
Confirm the BMW Z3 model year and fuel system connector style before installation. Because this is an in-tank assembly, access is typically through the fuel tank service area, and the tank should be handled with proper safety procedures. Verify inlet and outlet hose sizes, electrical terminal orientation, and sealing surfaces before final assembly.
Gasket or seal, strainer, mounting hardware, fuel sending unit, regulator, and wire harness are not included unless separately specified for your application.
