Franklin Fueling 708556901SA is a Remote Fill Splice & Tee Kit. It allows you to modify a standard drop tube for remote fill applications. The open tube design provides access to a Defender Series® overfill prevention valve (OPV) for remote testing without having to remove the assembly. The kit contains installation hardware as well as a gasketed splice which is then roll-crimped inside of the drop tube using the Defender Series® OPV installation tool.
