    Get with Jon@NP is you need specifics, but all you do is heat up the white feed straw so it's flexible on one end, push it over the pumps outlet and secure it with the clamp.
    Do the same thing on the other end.

    The pump will probably not fit exactly like the stock pump does. Install the filter and push the pump down into the bucket, the filter should hold it in tight enough, it's ok if it moves a little.
    Some drill a few holes in the bottom of the bucket as well.
    I gutted mine completely on the bottom, just don't run the truck with less than 1/8 tank.

    good luck,
    allen
