Hi everybody, first chevy first post. Just purchased, car was sitting in a lot for a while. Was running fine then I noticed a large amount of fuel dumping onto the ground under the engine. Popped the hood and saw one of the vac system lines (the one running from the fuel pressure reg.) completely unattached and spitting fuel. Reattached and was able it limp along a few blocks before all the fuel was on the ground and had to get it towed. Poked around when I got it back to the house and found the throttle body dumping fuel into the air filter. Took off intake manifold and fuel rail, injectors seem fine nothing looks messed up just really dirty. Don't really know where to go from here as this is the first car I've messed around with.
