I'm not familiar with the truck 6.4's oil filter housing,but could you clock the adapter so it was in a slightly differant position. If the nipple is the only thing holding the filter housing in place,i wonder if you could loosen it and re-clock the adapter. Another thing to consider would be to install a hose covering over the rad hose,to protect the hose from the filter,you're not gonna rub through the filter,but it also wouldn't hurt to protect the lower rad hose from filter rub through. If not there's always these.
