The two horizontal tubes go to # 3&4 carb intake runners. The T tube goes vertically to the PAIR valve operator. It's best to replace them now as they're out.
Thanks Sandy...I figured the elbow end went to that valve but did not know where the other hoses were supposed to go.
Desmog it and get rid of those lines.

thats what im getting ready to do.
Had planned on desmogging but I can't get the kit here in time. I have to go over to the office in Louisiana on Sunday.
