lower hose for edelbrock waterpump 502

I Just Got A 502 Built For My 70 Chevelle,it Has A Edelbrock High Flow Water Pump.my Problem Is, The Stock Big Block Lower Hose Is To Small Where It Goes On To The Water Pump.does Anyone Know Who Makes A Hose To Fit This Pump?

I've went to a parts store with the hose I had and asked if I could try to match a hose up that would fit. Some times you might have to cut some off to get it to fit. They also have flexible hoses if all else fails.
