on my 86 iroc i have a l4c carb. a big rubber black tube runs into the front of it. gas runs on top of my engine block not like a flood but definetly enough to notice and definetly can smell it? anyone know if this is a fuel hose or what and if the carb might be bad. whatever that hose is i think the gas might be escaping around the seal on the end next to the carb.
