The 'doodad' is a small reservoir. There should be a line from there to the thermostart unit in the front of the intake manifold. Swing the battery tray out and look down on the inside of the manifold near the rubber connection. Actually... remove the rubber and look in to see if there's any fuel running inside the manifold. If there is... replace the thermostart bulb. They're mabey 40 bucks or something. Not that expensive and well worth having.
