DISPENSER RETROFIT KITS
Dispenser retrofit kits provide the wires, couplings, and hardware needed to modify the hose and
nozzle to accept the fuel point hardware. They also contain the I/S Pre-amps and N-ring nozzle
antennas. These kits are described in detail in the Dispenser and Hose Retrofit Installation
Manual, C35593.
I/S Pre-Amplifiers (I/S Pre-Amp)
The I/S Pre-Amp assemblies are small PCB's mounted in
junction boxes within the dispenser. An I/S Pre-Amp amplifies
the antenna signal to the FPR, assuring reliable
communication. The Pre-Amps come factory-installed inside
a metal junction box. Wiring between the I/S Pre-Amp and the
Fuel Point Reader is shown in the System Wiring section of
this manual. Wiring between the I/S Pre-Amp and the nozzle
ring is shown in the Dispenser and Hose Retrofit Installation
Manual, C35593.
N-Ring Nozzle Antenna
The N-Ring nozzle antenna mounts on the base of the nozzle spout and is concealed by a special
nozzle cover. It is connected to the I/S Pre-Amp via antenna wire that is run down the inside or
outside of the hose. It transmits/receives communication to/from the vehicle's T-Ring antenna.
Installation of the N-Ring is detailed in the Dispenser and Hose Retrofit Installation Manual,
C35593.
VEHICLE COMPONENTS
Each vehicle is modified to work with the Fuel Point system by installation of a T-Ring tank
antenna connected to a Vehicle Module (VM). Vehicle installation kits provide the required
elements to install the T-ring and VM. Vehicle kit installation instructions are contained in the
Vehicle Module (VM) Installation Manual, C35699.
