Hanging Hardware
About the Hanging Hardware
Hanging hardware is the component that is attached to the outlet casting. This includes hoses,
nozzles, swivels, spacer hose, and breakaways. The hanging hardware is tested for leaks and
electrical continuity. The hanging hardware may be manufactured by companies other than
Gasboy. Ensure that you follow all manufacturer’s recommendations.
Hoses and Flow Restrictors
Inspecting Hoses
Check hoses regularly (at least once a week or upon complaint) for leaks and damage. Inspect
and replace the hose assembly, as required. The following conditions may contribute to
damage or problems.
• Twisting and curling puts unusual stress on hose parts.
• Repeated flexing of the hose in the same spot can cut, tear, or split the hose cover.
• Flattened hoses from vehicle drive-over can cause restricted flow and hose reinforcement
damage.
• A soft spot is a sign of internal damage to the hose reinforcement. Reinforcement may
appear through the cover.
• Loose or cracked hose couplings can cause fuel spills.
• Hose bulges are a sign of pressurized gasoline pushing against the cover. A full rupture
could occur at any time.
• Use of teflon tape for NPT hose ends may result in damage to the dispenser outlet casting
during assembly.
• Re-useable hose end couples are generally not recommended as improper repair/assembly
can cause leaks, lack of continuity, or hose separation.
• Use of excessively long hoses may create a trip hazard for customers. Use hose retrievers,
hose reels and so on, to eliminate trip hazards.
• Breakaways for low hose units must be attached close to the nozzle end, where the hose
clamp of the retriever is attached between the breakaway and the pump/dispenser hose
outlet casting.
• An improper location of the hose clamp may prevent the hose breakaway from working
properly.
• Severe injury, death, or equipment damage may result from a vehicle drive-off where the
hose breakaway fails to operate properly.
WARNING
Hose Retrieval Mechanisms
Hose retrieval mechanisms must be operational or a trip hazard may occur.
Replacing Hoses
Do not use soft-wall hoses. They can cause the unit to register with the nozzle closed when the
nozzle hook is first raised. Always use UL-approved hoses designed for the fuel being
dispensed. Read and follow all safety precautions. Follow OSHA Lock-Out and Tag-Out
procedures.
