Push Connect Fittings
SPRING LOCK COUPLING
The spring lock coupling is a fuel line coupling held together by a garter spring inside a circular cage. When the coupling is connected together, the
flared end of the female fitting slips behind the garter spring inside the cage of the male fitting. The garter spring and cage then prevent the flared end of
the female fitting from pulling out of the cage. As a redundant locking feature, a horseshoe shaped retaining clip is incorporated to improve the retaining
reliability of the spring lock.
FUEL FILLER NECK (FILL PIPE RESTRICTOR)
Fuel Filler
To prevent accidental filling with other than unleaded fuel, vehicles that require unleaded fuel have a special filler tube. This filler tube has a restriction
in it so that the only nozzles that can be inserted are the smaller diameter nozzles of pumps dispensing unleaded fuel.
