Simply adore my well loved and maintained by first owner 2010 LRRR HSE, V8, one problem after a year was fuel smell. Had fuel line replaced 12/06/16 by LR dealership with great service history on my vehicle and in my area. Told to give it a month b4 being concerned about gas smell remaining...

Could somebody help me identify what is this connector?? I can´t find the other side to which it should be connected... It´s a 92 NAS rangie. Thank you! (See attached picture)
