This is the F-F Union fitting to connect fuel line 3VZ To UZ Swap. 90404-14014 The original hard line on the 3VZ vehicles varies between Male, Female and Male w/ a F-F union. You will need to check and see what fitting your original hard line has in place. If you have a F end or M end w/ a Union from the factory, then the standard hose will work. If you have a Male end only, you will also need a F-F union. This is the fitting that you will need to properly connect the lines.
