The fuel pump is electric. It is located in the fuel tank. I replaced mine this past winter. Exhaust andrearend need to be lowered out of the way.I did this on jackstands would have been easier if the car had been raised higher in the air as you have to twist the tank to get the filler neck out of the rear qtr. I bought a GM pump ($80)from the local Chevy dealer --as a note it did not include the in tank filter ($16)which goes on the pump. I had to order it afterward and it held me up a couple of days.

Stay away from the 1968 which had several quality issues and is considered the worst Vette built. The 1975-77 were poor performers due to emissions standards. The 1983 is also another Vette I would avoid. There were no 1983s, I think you mean 84s cause that cross-fire injection is garbage. The 1982 model was cross-fire injected as well.
