My initial thoughts are -- you're dealing with parts that are too close together to make good plumbing bends etc. and I'm talking about how PARALLEL they are.. not the end to end stuff...
You've got to come out the Weldon pump -- and get over to the outlet side filter -- and dude! That's tight right there... You can do it with hard line -- but a 1/2" (AN -8) bender radius is 1 1/2" .... so you have to have space (length) to bend the tube - get a tube nut on and sleeve on - and then flare it.... and get that tight radius bent and then down over to the inlet of the filter before the regulator.
If it was me - I'd put all that IN LINE and keep that part super simple.
Better send that to Mark at BentFab!
