+1:thumbsup:Your 3/4" hose is absolutely adequate for your splitter.
16gpm from pump will take at least 5/8" or #10. Your cylinder will return 25% more flow from capped side when retracting, and that make 20gpm, which require a 3/4" or #12. So 3/4" to capped siide and 5/8" to rod side is minimum "adequate" sizes.....practically you choose 3/4" on both?!.....
