A fuel storage and supply apparatus (22) for a watercraft (10) incorporating a plurality of connections (50,66) penetrating a housing (32) in a single opening in a fuel tank (12). Each connection is sealed by a radial O-ring (56,68) so that the connection may be rotated about a longitudinal axis without adversely affecting the seal. A single opening (34) in the tank may thereby be used to provide connections for a fill tube (66), fuel tube (50), vent (86), and electrical penetrations (150) for an in-tank pump (136) or level sensor (156).
