Power Steering system flush

Gentlemen …

I’m ready to flush the power steering system on my '89 XJ40. I also purchased an inline filter.


Any advice on the best way to do the flush ? Which hose to disconnect to use as a drain ?

Is it OK to place the inline filter on the hose going from the reservoir to the pump (in that direction), I hope that’s correct because I ordered the filter to fit the larger hose.
