Well I'll start from the top. I have an 87 Elk with a 305 and it ran great for 3000 miles, after i bought it. Then the fuel pump went out, and i put a new one on. About a week after that the car just died on the highway. When i popped the hood gas was all over the top of the carb and the manifold. After it evaporated the car will start but then will immediatly shoot gas from the top of the carb. Not just a little i mean a lot. I took it apart cleaned it and put it back together. This didnt help though. If i clamp the fuel line down almost all the way it will run just fine. I dont know if its the carb or what. Its a Quadrajet.
