    Water separator

    Hello all.
    On my 2006 Mercury optimax 150 DFI serial No. 1B273623. The fuel water separator
    part number is 35-18458 4. What is the difference in the 35-18458 5?

    18458T4 is the valid part number.

    That other number you provided is something you found printed on a filter (an internal production number, NOT a part number).
