The usual culprits are on the return line, clean every hose with a rag that cleans oil and then remove wheels
start engine and use dry white tissues to check for oil leak by touching them to hose nipples and other joints to see for wetness, make sure to use the original constant tension 2 ear clamps and original hoses or hydraulic oil / atf rated hoses, regular rubber hose swells and melts
Dont omit the end boots, if they are full of oil. Then the rack seals are leaking.
When doing final install, make sure to clean the bottle (it has screen in it) or renew it if its bady plugged and use upgraded viton or green hnbr orings
