Abstract
A filter arrangement disposed within a fuel tank and adapted to prevent vapor lock. The filter arrangement is comprised of a fuel sucking section which is communicated through a connecting pipe section with a fuel pump. The fuel sucking section is provided with a netting member through which fuel in the fuel tank is sucked into a chamber defined inside the fuel sucking section, upon operation of the fuel pump. The fuel sucking section is formed with a through-hole through which fuel vapor staying inside the fuel sucking section is releasable out of the fuel sucking section. Additionally, a valve mechanism is provided to normally close the through-hole but open the through-hole in presence of fuel vapor inside the fuel sucking section, thereby effectively preventing fuel vapor from sucking into the fuel pump.
