Does anyone know how I can fix a leaking bypass hose insert , and if so where do I get all the parts for it. It's the insert that goes on the intake and connects to the water pump by a 4" heater hose. Is that insert removable, and how do I take it out? Thanks in advance.

p.s
Just wanted to say thanks for all the help in the past to everyone. My galaxie should be running later this year. It takes a while when you have a wife and son that also need your attention.
