This patent describes a fuel tank for use in a motor vehicle, comprising: a bottom wall having a first planar portion and a second portion, the second portion extending downwardly from the first portion to form a chamber portion in the tank, the chamber portion having a bottom below the plane of the first portion, a fuel inlet pipe having an inlet with a detachable cap and an outlet end in communication with the tank, the outlet end being spaced from and open to the bottom of the chamber portion, a baffle of sponge-like porous material fixed in the chamber portion. The baffle includes a substantially plate-like portion spaced from and transverse to the outlet end of the fuel pipe and is located between the end and the chamber portion bottom for reducing the formation of fuel vapor caused by bubbling during the filling of the tank through the pipe.
