Fuel switch location on 1993 4 wheel drive ford f-150?
Maybe one of the kick panels
if you are talking about the safety switch it is on passenger side kick panel just feel around for the switch or remove kick panel. if you mean switch to switch tanks it is on your dash it changes the fuel pumps in tanks if you have duel tanks if you have a single tank there is a lil relay in the same place on dash. behind dash panel by head light switch.
