In tank fuel pumps on stock carbed engines???
Not sure if its a myth or not, but I read somewhere that some of the LG4s had in-tank fuel pumps to assist with the mechanical ones. My car is originally an 86 firebird SE and sported the anemic LG4 and a 700R4 auto. Can anyone tell me if I've got the mystery pump or If I'm just really gullable. I'm trying to figure out a fuel delivery issue and don't want to be surprised when I drop the tank.

It is true, some did have it. Some did not come with them but were retro-fitted by dealers per a TSB.
Most likely you don't have one; but the only way to know for sure is to look.
