Engine Mechanical problem
1990 Chevy Cavalier 6 cyl Front Wheel Drive Automatic 130000 miles

Hello I am working on a 1990 z24 n im having trouble dropping the tank to get to the fuel pump and replace it. Is there any other way to get to the fuel pump I looked under the back seat and there was nothing there I took to bults in the front off and it looked like almost a hinge I coulndt pull the tank down found two bults in back and cant get them off they will not spin I have put penatration oil and everything on them nothing. Would it be safe just to bend the straps remove n replace the pump and bend back to place? Wat could I do

Do you
