Pro tip from the oil line job on Lilia.
Push the hose in as far as it needs to go. On this side, pull it a little and make sure there's good flow through it. From the looks of it, there is.
Make sure the hose isn't stuck or crimped in any way, shape, or form. The last thing you want is that line stopped up, especially when you're trying to drain it.
Then move it into position.
