fuel control valve 700 1988

HI: I have just found a condition on my non-turbo 1988 B230F engine. After running it hard, Flooring it till I am at about 75 or 80 mph ( this was a emergency run to a local hospital) I openend the hood and noticed only 1 strange thing, and that was the control vaccume hose that puts vaccume to the FCV ( fuel control valve) it was almost off the connection nipple on the fuel regulator valve (or some people call it a fuel control valve-whatever) . What would be some of the posible causes of this happening? Any idea's would be welcomed. Also, it is the original and the engine has 136,000 miles on it, but it runs great. But if that vaccume hose comes off while running it I'll have a instant problem of fuel starvation, please help. Thanks ,Dan.

    I'd say you need a new vacuum hose. Replace them all while your at it. Use the correct size hose.
