as mower man says, there should be a short length of pipe attached, but they tend to get broken off in transit.
you could try and get a replacement from ford.
GBS make an alloy replacement which pushes in after removing the plastic bit, and you add a short length of fuel hose.
and I have seen an adaptation using what’s left of the plastic bit with the addition of a piece of brake pipe, flared at one end, pushed through the hole from inside and bent into a coat hanger hook shape on the outside.
however you do it, remember that the plastic bit has an alignment notch which should be matched with a mark of the casing, as its the shape of the plastic bit inside the diff that prevents the oil coming out.
