Can't find fuel filter on 1999 jeep cherokee

By now you probably found it, but, if not, it's on the inside of the chassis rail, about even with the front of the left rear tire. If not there, then it's inside the tank, part of the fuel pump sending unit (I know...dumb)
When changing it new filter is labeled in and out. "out" side goes towards engine If not labeled this way it may have an arrow (points to engine). When disconnecting it, wrap a rag around it to prevent squirting gas in your eyes. Don't have your head directly under it either. Have the new filter ready to install so too much gas doesn't go all over the place.
Good Luck
