i have a 91 firebird with the 5.0 is there anyway to do the fuel pump without dropping the tank

 

Do a search, there's ways but you have to cut up the body, I say just get at it its not that hard to drop a tank

 

If you cut the hatch area to make an easy access hole, you'll have to cut all 4 lines of the sending unit and install high pressure hoses. Ive seen it done but I recommend you doing it the right way. Dont be lazy. Get dirty and getter dun. Plus you'll get to clean out the tank.
