Default air pump issue

First of all hello all. I have a 73 coupe 350 at, The main hose from the back of the pump keeps blowing out of the housing. It is the main hose that splits off and goes to each exhaust manifold. any ideas why this is happening?
not sure it matters but it has been rebuilt to a 383 basically stock.

Thank you

Maybe one or both of the check valves (at the top of the AIR manifolds) has failed, and the exhaust backpressure is going back into your hoses.
