In many cases of fork seals leaking, the seal does not need to be replaced – it just needs to be cleaned.
Pull up the dust boot, and, using a piece of thin flexible plastic about one inch wide and maybe 2 1/2 inches long (25 mm x 64 mm), slide the plastic piece down the fork leg between the seal and the fork slider. Once you learn to bend the plastic to make a contour that fits the fork slider, it is easy to do.
Moving the plastic piece up and down, go completely around the fork slider a few times. It should go to a depth of about 1/2 inch or 13 mm.
Doing this removes the dirt trapped between the fork seal and the fork slider, and, in many cases, will stop the fork seals from leaking.
