Hose. Fuel-dispensing hoses must withstand the effects of sun, cold, and heat, as well as jerking and pulling from customers, all the while safely containing a flammable and toxic liquid.

Conventional and Vacuum-Assist Vapor-Recovery Hose. Remove the nozzle from the nozzle cradle and carefully look at the entire length of the fuel hose. Check the hose for kinks, blisters, bulges, flattened areas, soft spots or any cuts or gouges deep enough to expose the wire or fiber reinforcement beneath the cover of the hose. Pay particular attention to any portion of the fuel hose that is routinely touching the ground or the dispenser island, as this is a location where wear may occur. If you find any problems with the hose, remove the nozzle from service until it can be repaired or replaced.

Balance Vapor-Recovery Hose. Remove the nozzle from the nozzle cradle and carefully look at the entire length of the fuel hose. Check the hose for kinks, flattened areas, or any cuts or gouges deep enough to expose the wire or fiber reinforcement in the outer hose. The hose should not touch any portion of the dispenser island or driveway when the nozzle is in the cradle. If you find any problems with the hose, remove the nozzle from service until the hose can be replaced.

Hose Fitting. Inspect the fitting at the dispenser end of the hose to be sure it is clean and dry. If the fitting is stained or wet with fuel, remove the nozzle from service until it can be repaired or replaced.

Swivel fittings have moving parts which are susceptible to wear.  Wear should be checked by testing to see if a dime can be inserted between the bottom of the swivel nut and the fitting hex nut.  If this condition exists the hose should be removed from service.  See the diagram below:
