TBI's are dirt dumb simple.

It was common for the fuel pressure regulator in the TBI to get weak and they are cheap/easy to change. TBI has a supply and return line.
As stated, fuel pump maybe and/or frame filter.
Yes they are easy to replace (regulator). Ones biggest worry in that job? Dropping one of the bolts down the TBI throat while disassembling or reassembling it.
Take your time and more importantly carefully fold Scott's towell or such over the TBI throats before working on it.
Those regulator diaphragms are made of Viton and do not fail often and generally do not strand one. There really isn't much to rebuilding one given the kit is primarily made up of seals. I've rebuilt them without even taking the TBI off the intake. It can be done if your certain the intake manifold gasket is good.
As long as one makes it a good habit to replace the fuel filter every 15k the TBI will live a long life. Likely longer than the owner.
