I just added a rear tank to my 73 clubcab. My question is: has anyone else done this to a truck that didn't have it, and where did you locate the fuel filler inlet? I'm not going to run a rear bumper, so that is one location I can explore. Looking for ideas. Thanks so much. ps., I bought a black tshirt on Facebook with pic of an orange 73 today. Can't wait until it comes. My truck is orange.
