Question about 2003 Harley Davidson FLSTCI Heritage Classic
Sounds like a vacuum line. If the bike runs without it with no problems, you can tie the line up, and plug it - however, I suggest trying to reconnect it to prevent further issues - as a broken vacuum may cause lack of power do to the lack of proper vacuum.
If it comes of the carburator, it most likely is one (if more than one, should only be one or two for this size engine) that connects to the airfilter housing, or to the back side of the carborator.
Please let me know if you need further assistance.

Carbuerator control coil is routed arround the right side of the steering hand between the right gas tasnk lower mounting tab and gas tank.And through the carbeurastor control coil bracket to the carbeurator . The bracket is attached to the top motor mount. This bracked it angled to meet the coil coming around the right of fromt down tube. A rubber boot connects the carburetor to the intake manifold, secured with 2 3mm Allen head, Phillips or slotted head hose-type. to remove the carburetor from the boot, leaving the boot connected to the manifold; thus, loosen only the bolt for the clamp on the carburetor side of the boot. Ease the carburetor out of the manifold boot; note the position of the notch on the boot that aligns the carburetor into place. Disconnect the choke knob from the mounting bracket on the left side of the bike; leave the cable connected to the carburetor. Leave the idle adjustment cable and the fuel line connected to the carburetor. Label and disconnect the remaining 2 lines on the back of the carburetor. One is the carburetor vent line going to the evaporative canister or exiting just forward of the rear swing arm or inside the right side cover; the other is the vacuum source for the fuel petcock and the air switch valve . Label each of the two throttle cables and its position on the carburetor; disconnect the cables. Loosen but do not remove the 4 Phillips head bolts holding the domed plastic cover (top of the carburetor) in place - there is a spring under this cover that may launch the cover and bolts away from the work area if the bolts are completely removed. Holding the cover down, remove the bolts. Set the bolts aside someplace safe. Carefully remove the top cover and the spring pushing it up; set them aside someplace safe. Examine the black rubber diaphragm inside the carburetor attached to the slide. Be EXTREMELY careful with this diaphragm; if it is pierced, torn, or twisted out of shape, the entire slide assembly must be replaced. Thanks. Keep updated for any more query. You can rate this solution and show your appreciation.
