    Twice in the last three months, I have had to replace the 20Amax fuse under the hood of my F250 as the fuel pump goes into failure.
    I'm figuring a wire chafe somewhere as both times it occurred were rainy days.
    Without dropping tanks, where would most likely such a wiring issue occur?
    TY.

    Increased load can cause the pump to draw more amps.
    When was the last time the fuel filter was changed?
    The fuel pump sock (pre-filter) in tank filter changed?

    Worn brushes at the commutator pump motor shaft can also cause more
    than average amp circuit draw.

    Without a clamp on type amp draw detection test meter, you already know
    the fuel pump circuit is overloading. Visual inspection of the wiring from fuse box
    and relay to fuel tank will give you the indication of a "shorting out" condition.

    If you do not find any area of wire abrasion, you may have one of the problems I
    mentioned before.
