i just did my intake gaskets i believe the leak is in the gaskets but my question is the o rings on the in and return fuel lines if they are worn could they cause a suction leek and cause the car to not idle and stall imediatley after it firing up the car is an 88 305 auto

 

In a word, no. You'd just have leaking fuel. Best test is to spray carb cleaner at spots you suspect the leak, if the engine reacts to it, that's your leak

 

def intake just weird she ran good shut it off came home from work and wouldnt run but i think it sounds like driver side leak i'll do gaskets again and try it
