The conduit has fuel filtration means having a cylindrical wall with a number of openings for preventing particles of dirt from infiltrating between the seat and the shutter, without producing an excessive fall in fuel pressure. The thickness of the cylindrical wall is less than 1 mm, and the width of the openings is less than 0.25 mm.
