I couldn't get the original hose out either. Like you said, it seems like it was epoxied or just really jammed in there. I ran a new hose along side the original, and hooked that up to the pump. The hose is quite a bit smaller than the original, so that it would hook right up to the pump. So, at the cooler drain, I had to cobble together a few hoses together with some adapters to reduce the sizes and fit everything together. I'm sure it wasn't the "right" way to do it, but it works great.
