If the sub tank upper member 85U and the sub tank lower member 85L are integrally formed, the assembly process is reduced.
- the pressure loss of the upper filter cloth 16U and the pressure loss of the lower filter cloth 16L may be the same.
- the pressure loss of the lower filter cloth 16L is the upper filter cloth. It is set lower (smaller) than the pressure loss of 16U. Thereby, first, more fuel passes from the lower surface filter cloth 16L and flows into the fuel filter 16, so that the state in which the fuel is stored in the storage member 18 can be maintained.

May be. Even when three or more filter media are used, a bag-like fuel filter can be formed as a whole by joining the filter media at the joint. Then, a sandwiching position may be set at a position different from the joint, and the filter medium constituting the fuel filter may be sandwiched.
- the upper sandwiching wall 30U and the lower sandwiching wall provided in the above-described sub tank upper members 15U and 85U (sandwiching pieces) and the sub tank lower members 15L and 85L (sandwiching pieces). It is not limited to 30L.
- the fuel filter 16 a plurality of filter media
- it may be a member that exhibits the effects of maintaining the shape of the fuel filter 16 and ensuring the strength. Good.
- the upper sandwiching wall 30U and the lower sandwiching wall 30L are both formed in a cylindrical shape, and the sandwiching position NP is annular.
- the “clamping position” of the present invention does not need to be set in an annular shape with respect to the filter medium (upper surface filter cloth 16U and lower surface filter cloth 16L).
- the shape set discontinuously in the direction along the outer periphery of 16 may be used.
- the relationship between the storage member 18 and the fuel suction pipe 44A is not limited to the above-described relationship.
- the fuel suction pipe 44 ⁇ / b> A may be configured to penetrate the lid plate portion 22 at a position different from the inflow hole 24 of the lid plate portion 22.
- the storage member 18 may not cover a part of the fuel filter 16 (a part of the fuel filter 16 protrudes outward from the storage member 18 when viewed from above). In this case, if the fuel suction pipe 44 ⁇ / b> A is connected to the protruding portion of the fuel filter 16 (outside the storage member 18), a structure that does not penetrate the cover plate portion 22 can be achieved.
- the fuel pump module 32 having the fuel pump main body 42 is described above.
- the fuel pump main body 42 is not necessary.
