PRINCIPLES OF OPERATION

Connecting a hose from a fuel truck or other fuel source to the filler/discharge hose assembly fills the

collapsible fuel tank. This assembly is connected, in turn, to the gate, ball, or butterfly valve that has

been connected to the filler/discharge assembly. Gate, ball, or butterfly valves are used to control the

flow of the fuel.

Connecting the filler/discharge hose assembly, and gate, ball, or butterfly valve to the filler/discharge

assembly discharges the collapsible fuel tank. Water, sludge, and residual fuel are drained through the

drain hose assembly at the bottom of the tank. The fuels are extremely hazardous, and all safety

procedures must be strictly followed.

The vent and pipe assembly contains a relief cap that opens automatically when the tank vapor reaches

an internal pressure of 0.10 psi (0.0068 atmospheres).
