    Abstract: An adjustable length column pipe for connecting a submersible electric pump in a fuel storage tank with a distribution head that distributes the fuel to dispenser units. Two telescoping column pipes can be telescopically adjusted to the desired length and then locked together by a locking mechanism. An adapter bushing is threaded onto the end of the larger diameter pipe and has a projecting sleeve. A fitting is threaded onto the sleeve and tightened to compress a seal ring which seals the lock assembly to the pipe. Projecting fingers on the fitting are wedged against the smaller telescoping pipe by a nut which is threaded onto the fitting and has a tapered surface to provide progressive wedging action. Electrical wiring for operating the pump is contained within a telescoping conduit assembly which extends inside of the column pipes and is isolated from the fuel passageway by a seal arrangement.

    Abstract: A casing which provides a fluid and electrical interface between components of a fuel dispensing system. A column pipe which receives fuel pumped from an underground tank connects with a power head mounted in the casing. A check valve controls flow from the power head to a dispensing pipe leading to a fuel dispenser. A hand operated quick connect coupling connects the power head with the check valve housing to facilitate extraction of the power head, column pipe and pump. The check valve element can be removed along with a cover to the check valve housing. Leaking fuel and excessive fuel vapor are returned to the tank by valves. Fuel from the check valve housing used to operate a siphon system is returned to the tank along with fuel needed to relieve excessive pressure in the check valve housing. A junction box in the casing houses electrical wiring and is equipped with a safety barrier plug that accommodates a signal wire from a pressure transducer used to control the fuel flow to the dispenser.

    Abstract: A spool assembly which provides for field adjustment of the column length in a pumping system such as that used in gasoline dispensing. The spool assembly is installed between a submersible electric pump and a discharge head. The spool assembly includes a head spool, a base spool and a column pipe which connects the head and base spools. The spools have electrical connectors which automatically make electrical connection to supply power to the submersible pump motor. A liquid flow path is provided through the spool assembly and is isolated from the electrical circuitry.
