Yeah, getting hoses is a pain. I took a tig rod and bent it how I thought the hoses should be. Went to my local mom/pop auto store and they let me look at all the hoses in the back. Sure as ****, found what I needed for both hoses.
In the pic above with the outlet turned upwards, I’d get a hose that has some of the right bends for both ends and use a stainless or aluminum tube to connect both ends. Aluminum will be easier to put a “bump” around the tube so the hose clamp can’t come off while under pressure. Hell, ya could even tig weld a band around either one if ya have access to it.
