Abstract: A portable, cryogenic fluid pump apparatus with associated instrumentation, conduit legs and accessories, are optimally configured on a modular supporting platform for plug and play installation at a filling station and on-site inspection and maintenance at the filling station. Each of the associated instrumentation, conduit legs and accessories are positioned onto a condensed footprint such that access to the platform is possible. The plug and play connection system allows for the rapid connection or disconnection of the various instrumentation, conduit legs and accessories on the modular supporting platform to a vaporizer and a source tank at a filling station. The connections or disconnections may be made safely, quickly and, easily in advance.
