Abstract
A pass-through device for internalized component fuel tanks provides passageways for communication between the interior chamber of the fuel tank and the exterior. The pass-through device includes a communicative passageway for a fuel supply line and a through opening for electrical connections, and may include additional communicative passageways for fuel return lines, and purge and fresh air inlets. The pass-through device includes a main body preferably composed of nylon. The main body is bonded to a mounting plate preferably composed of polyethylene. The mounting plate provides a circumferential surface for weldably sealing the pass-through device to a polymeric fuel tank.
Claims15
A pass-through device for a polymeric fuel tank having internalized components accessible through a main opening, the pass-through device comprising:
- a main body having an upper surface and a lower surface said main body having an outer diameter smaller than the diameter of said main opening;
- a mounting plate comprising a circular member defining a plurality of openings, a recess and a circumferential cap, the mounting plate having an outer diameter larger than said diameter of said main opening, a portion of the mounting plate extending beyond the outer diameter of said main body to define a circumferential ridge in conjunction with said main body;
- said main body further defining an axially extending raised portion sized to fit within said recess, said raised portion having a groove and said circumferential cap defining at least one projecting lip, said groove and said projecting lip interacting to retain said mounting plate adjacent said main body;
- and
- at least one communicative passageway extending from said upper surface, completely through said main body and said mounting plate;
- whereby said pass-through device can be secured to the polymeric fuel tank by welding around said circumferential ridge.
A pass-through device for a polymeric fuel tank having internalized components, the pass-through device comprising:
- a main body having an upper surface and a lower surface and defining a fuel supply line port and an electrical supply line port;
- a mounting plate comprising a circular member defining an axially opening recess and a circumferential cap, the mounting plate connected to said main body and extending beyond said main body to define a circumferential ridge;
- said main body further defining an axially extending raised portion sized to fit within said recess, said raised portion having a groove and said circumferential cap defining at least one projecting lip, said groove and said projecting lip interacting to retain said mounting plate adjacent said main body;
- said main body and said mounting plate having a corresponding plurality of openings that define an electrical supply line port, a fuel supply line port and a fuel return line port, said electrical supply line port being centrally located within said main body and mounting plate, said fuel supply line port and said fuel return line port being radially spaced from said electrical supply line port and;
- whereby said pass-through device can be secured to the polymeric fuel tank by welding around said circumferential ridge.
