what tranny do i have.. fuel line problems

have an 83 full size bronco.. 302 automatic.. reverse went out, and going to get another tranny.. is it a c-4.. if so what other ford motors mounts up to a c-4..


have a problem with it building gas pressure up.. it has a mechanical fuel pump on motor and also the person i got it off of put on a electric pump on the front driver side fender well.. takes elec. pump 10 minutes to pump up gas to it during first start up of day.. mechanical pump is good.. bad fuel lines or something wrong with inside of tank??

It could be an air leak ?
