Abstract: An atmospheric box for use with a fuel vent pressure sensor is operatively connected to a fuel tank of a vehicle. The atmospheric box includes a base including a floor, a sidewall extending upward from the floor and having an outer perimeter, and a drain hole opening in the floor, and a cover including a top section, an outer wall extending downward from the top section and having an inner perimeter substantially similar to the outer perimeter of the sidewall, thereby creating an interference fit between the cover and the base. An inner labyrinth wall extends downward from the top section inward of the sidewall, and a tube joint in the cover defines an opening inward of the inner labyrinth wall. The atmospheric box provides access to the atmosphere for measuring pressure while blocking water and debris intrusion.

Abstract: A blow molded thermoplastic fuel tank with built-in fuel system components inside of the tank on separate and spaced apart internal brackets reduces the detrimental effects of thermoplastic swell to ensure fuel volume capacity is maximized, and appropriate clearances with the fuel tank wall are maintained. An internal configuration with separate spaced apart brackets provides more design freedom in the shape and configuration of the tank while enabling the tank shape to be thinner overall and fit within tighter spaces. The separate brackets also act as baffles to prevent sloshing noises of liquid fuel in the tank.
