THRU COOLANT WOES

We recently decided to add a Schunk hydraulic tool holder with a thru collet sleeve to our drilling operation on a Brothers S1000x but we are having an issue.. the thru coolant wants to fan out instead of staying down on the tool.

A few things we have tried...

replaced the thru coolant sleeve (just incase is was defective)

played with the PSI (upping to 700psi and reducing 300psi) no change either way. normally we run 435psi


short of re-plumbing the whole machine with larger coolant hoses to increase volume not sure how to fix.
you'd think it would work out of the box

Has anyone running this type of set up have similar issues?
