<P>PROBLEM TO BE SOLVED: To efficiently exhibit metal ion removing performance of a metal ion trapping material in a fuel filtering device to which the metal ion trapping material is incorporated. <P>SOLUTION: The fuel filtering device 1 is provided with a first filtering body 4 formed by the metal ion trapping material for trapping metal ions in fuel 21A; a second filtering body 5 formed by a filtering medium for trapping material particles in the fuel 21A; and a case 9 for storing the first and second filtering bodies 4, 5. A water storage space 81 for storing water separated from the fuel 21A is provided below the second filtering body 5 inside the case 9, and at least part of the first filtering body 4 is arranged in the water storage space 81. Thus, metal ion removing performance of the metal ion trapping material can be efficiently exhibited. <P>COPYRIGHT: (C)2009,JPO&INPIT |
