Any tips on downsizing this from the manifold 1" water pump 0.8?

Use one of these in the intake and one in the water pump if you want to use a 3/4" bypass hose:

Or one of these in the intake and one in the water pump if you want to use a 1" bypass hose:

Better priced one:

The barbed tip on either of these will seal better with the hose, so I recommend replacing the ones you have with one size of these...

The 1" size is much cheaper for the fittings though... You may want to check other places...
