Welcome to Ford Truck Enthusiast ! I just approved your being a member of FTE's Indiana Chapter. I even created a thread to welcome you :
https://www.ford-trucks.com/forums/1...tuffy1960.html If you questions about your 1993 F250 I'll reccommend you look in the 1987 to 1996 F Series forum or the 6.9/7.3 L IDI engine forum.
