The cold start injector line is probably just fine, but the O-ring inside is junk. The kit with all new O-rings for the cold start injector system is $18, but you can go to http://www.mcmaster.com
and order a package of # -105 O-rings in Viton (not Buna-N or nitrile like common parts store O-rings are typically) for around $5 plus shipping. Make sure you get Viton, other materials will fail quickly due to the heat in that location.
BTW, I cropped and resized your pic and put it here: http://www.fierocentral.com/images/misc/coldstarttubeleak.jpg
you can right click/save as and replace the mongo pic you have here now.
