ABSTRACT:
A fuel filter arrangement includes a core member and a filter main body. The filter main body includes an inner filter and an outer filter, which is arranged at outside of the inner filter. A pore size of the outer filter is greater than a pore size of the inner filter. The inner filter is formed by immersing the core member in a high-density fiber solution and generating an inward flow of the high-density fiber solution through the core member. The outer filter is formed by immersing the core member, around which the inner filter is formed, in a low-density fiber solution and generating an inward flow of the low-density fiber solution through the core member and the inner filter.
