I have a coolant leak somewhere near my water pump but can't find it I have replaced the water pump and water pump hoses but it's still leaking what is the next step in finding this leak ?

Put a pressure tester on it. Remove all the underbody panels. Keep searching until you find it.

The bleed hose from the expansion tank to the top of the radiator hose has plastic pipe in the middle of it don't over look that and if it's old replace it, also the expansion tanks are crap plastic

I agree with both of the above answers, but have to ask: You DID replace the thermostat when doing the water pump, didn't you? Because that's an ugly job to have to do twice....
