Car problems. Cars not getting enough fuel.?

Question

Alright i have a problem with my car, 87 crystler 5th avenue. Its acting like its not getting enough fuel. Now ive replaced the Fuel Filter, Fuel Pump, Fuel Lines and Cleaned the Carburetor and still the same thing it acts as though its going to die but wont die as though its not getting enough fuel. I was told its the Gas im putting in my car I understand that, I know the things about the Ethanol in the gas and the causes it has with older cars but all the Stations down here all have Ethanol in it. Is there something i can put into the gas or something i can do to fix it. This is the ONLY car I have and i have no money for a new car by far even a used one.

Answer 1

there is a gas treatment that you can put to kind of clean things up. it's called gas treatment lol but this may not be it. it may be the battery?? or anything else for that matter

Answer 2

No . Your problem is that you're losing pressure due to bad gaskets.  

Answer 3

when you replaced all that stuff, did you bleed the air out of the lines?
