Just saw your post, ARK. I replaced all hoses on the earlier of the 2 4300s I rebuilt.
I went with standard-length pre-made 1/4" hoses from SurpCntr, and JIC-to-ORFS
fittings from DHH. 90-deg adapters from them, two. Cost less than custom hoses.
Some of these JD FELs have restriction adapters in the hose....1/4" hose is a benefit.
Works great.
