means it can perform its function on or off the fueling nozzle. If the nozzle tag is not secured to the
nozzle, the nozzle tag may be removed and placed next to a filler neck ring of any vehicle with an
authorized AIM2™ module. This will actuate the hose the nozzle tag was removed from permitting it
to fuel anything the nozzle is inserted into. Installation must
provide for security of the nozzle tag.
Nozzle tags should be secured to fueling nozzles by placing a clamp around the nozzle tag as shown
in Figure 3-2. CV joint boot clamps which require a special tool for installation provide the best
security because of their difficult removal. Kits are available through Syn-Tech Systems which
contain some of the more common nozzle tags and a CV joint boot clamp (see Table 3-1). CV joint
boot clamp pliers (Figure 3-1) are required to install these clamps, and are available through any
automotive parts outlet.

Nozzle tags have been developed for a wide variety of fueling nozzles to include Stage 1, Stage 2,
vacuum assist, and balanced vapor recovery, Emco Wheaton Posi/Lock, Healy EVR, and others.
Nozzle tags may be cross-referenced to the fueling nozzle being used. Use Table 2-2 to select a
nozzle tag for the fueling nozzle in use.
Nozzle tags may prevent the normal hang-up of the fueling nozzle after the transaction is complete.
Figure 3-2 also shows an example of a Nozzle Hang-up Extension installed to permit the nozzle to be
hung up on the dispenser after a nozzle tag is installed. The extension shown was manufactured by
the customer. We are not aware of any nozzle hang-up extensions commercially available for this
application.
Selecting the Correct Filler Neck Ring and RFID
Extension Cables
Filler neck rings must 1) fit around the filler neck of the fuel tank, 2) allow the filler cap to be installed,
3) permit the nozzle tag on the fuel nozzle to be brought up against (or parallel within 2 inches) of the
filler neck ring, and 4) connect to the RFID Interface Module (Lump Board) installed in a protected
mounting location. All this must be considered when selecting the correct filler neck ring.
The appropriate RFID Extension Cables in the correct length must be selected to connect between
the RFID Interface Module and the AIM2™ module. It may be prudent to opt for a longer cable if the
needed length is close to one of the cable lengths. All the AIM2™ vehicular equipment may one day
be transferred to another vehicle, and the additional length may be needed. RFID Extension Cables
should not be extended or spliced.
