Default 5.3 LS1 manifold truck water pump?
My install seems to be going smooth until my throttle body hits the edge of the water pump line. Any suggestions to get around this?

No leaks from twisting?

I actually pulled it right out, twisted it and re-installed with some gasket sealer - I forsee no problems but have not ran it yet. I stuck a dowel that fit in the hole and it came right out.

If it's a DBC throttle body, you can just dimple the neck in a bit, it doesn't take much.

I'm using a water pump from a 2007 truck. Water neck clears without issue.

I've done this by heating the waterpump around the neck and pulled it out. Using a green loctite 908 I think , I clocked it where I wanted an pushed it back in.
