<p>A vehicular fuel supply apparatus in which a sub-tank 21 that is inserted into and attached to the bottom wall opening 1b of the fuel tank 1 has integrally formed therein by molding a fuel chamber 24, support cavities 7c, 22c, 23c and a fuel flow paths 27 and 29, and a fuel pump 7, a fuel filter 22 and a pressure regulator 23 are accommodated and supported within the respective support cavities. The fuel chamber 24 is substantially closed against a rush flow of the fuel except for the air vent hole 24b and the fuel inlet port 24a through which the fuel flows at a predetermined flow rate per time, and has formed in the wall surface of the fuel pump support cavity 7c a groove 38 for accommodating and supporting a power supply line 11. Parts for assembling the components or elements of the apparatus are not necessary and the weight and the parts number is decreased, resulting in an easy assembly and a small cost. Also, the fuel does not flow out from the sub-tank even at the time of the abrupt acceleration or deceleration of the vehicle. <IMAGE></p> |
