Sliding braided over a nipple an putting a clamp on it isnt a very good clean install. Cant you just omit some of that crap? Maybe some of the kevlar braided stuff would accept a clamp better. You will have to look around summit, the best thing I can think of is a fitting that would A: attach to the stainless braided like an AN, you slide the female threaded collar over the line, then oil up male dinggie on the other half of the fitting. Jamb the dinggie into the rubber braided, and get all the little stainless wires inside where they belong, an then put a tiny bit of oil on the threads and thread the 2 halfs of the fitting togehter. that will attach the fitting to the stainless braided and seal it up nice like.
now on the other side of the fitting, I think i saw some that sleeved over a hard line of sorts, like what you have hanging off the parts on the block. there was a releaf cut in the sleeved part and a pinch bolt(s) to clamp and seal it against the hard line. But for the life of me I cant remember what they call the fitting. I think you can picture it in your head the way I explained it.
I can’t eliminate anything as far as I know. It’s really just a heater core and oil cooler :lol
I was all over Summit but just open to ideas from people that have worked with this kind of thing before. The biggest issue I think is the sharp bends for the oil cooler and heater core.
