Can't be sure exact place, But it has to be before the fuel primer pump. Tank, tank outlet line to the strainer, up to the fuel primer.Everything after the primer is under pressure. A test would be to attach test line at the primer pump inlet, and back into a fuel container or into the fule tank filler opening and run test.
