Abstract: An improved portable fueling facility for aircraft or ground vehicles includes, in the disclosed embodiments, at least one storage tank, an outer tank for providing secondary containment about the storage tank, a fill pipe and connection cap structure for communicating an outside end of the fill pipe with a source of fuel. Advantageously, the connection cap includes a screen for removing particulate matter from fuel that is introduced into the storage tank during refueling. A second aspect involves a compartment that is defined about an outer second portion of a pipe such as a fill pipe for collecting and containing any fuel that might spill during use.
