ABSTRACT:
The present invention relates to modified fuel tanks for use in watercrafts and, in particular, to the use of a fuel cell in a fuel tank to concentrate fuel about the fuel intake line to prevent air from entering the fuel intake line due to shifting of fuel within the fuel tank. The fuel cell includes a body portion having four walls defining a rectangular inner chamber. Apertures, preferably square apertures, are formed in the port and starboard walls of the fuel cell. These permit fuel to enter the fuel cell as the fuel shifts within the tank. Additionally, at least one small aperture is formed adjacent the base of the fuel cell to ensure that the level of fuel in the fuel cell is always at least equal to the level of fuel in the fuel tank. Inner and outer mounting plates are used to mount the fuel cell to a standard fuel tank. The outer mounting plate is also adapted to receive fuel intake and return lines, as well as fuel gauges.
