COMPONENT OVERVIEW
As you read the following descriptions, refer to the
drawing at the right for an overall view of the
assembled hose.
The GASBOY Fuel Point system requires
modification of existing pumps and hoses using
retrofit kits or installing internal-wired, factory-
assembled hoses. Each hose outlet requires a
Fuel Point Amplifier available in single, twin or 2-4
hose multiple product assemblies. Hose retrofit
kits provide the parts for field modification of UL-
approved fueling dispensers and pumps. To
discourage tampering, hose wiring is internal to the
hose or enclosed in flexible metal tubing.
Connectors are concealed by PVC covers and the
breakaway connector can be reconnected after
drive-offs
Hose assemblies and kits are available in a variety
of configurations for UL-Listed ¾” and 1” standard
and most Vapor Recovery style nozzles. Kits can
be assembled differently based on the breakaway
location. A list of kits and assembly instructions
are discussed later in this manual. Kits include
parts shown in the diagram at right except hoses,
nozzles and fuel breakaway which are to be
supplied by the installer. Wired hoses include
same parts plus the hoses.
The N-Ring assembly (nozzle antenna) mounts at
the base of the fueling spout of the nozzle. The N-
Ring transmits and receives communications to
and from a Fuel Point-equipped vehicle via a T-
Ring (tank ring antenna).
The hose wire provides communications between
the N-ring and Fuel Point J-Box/Amplifier mounted
in the base of the pump. Internal hose wiring
enters and exits the hose through special brass
fittings outfitted with O-ring compression seals.
Hose wires are constructed with a factory-installed
slack loop to compensate for hose stretch that can
occur during a drive-off.
