FWIW, here is how I ran the front cooler line for more clearance, and switched to 3/8" SD hardlines at the same time.
1- Edelmann 822560 fitting $11 on Amazon
SD 3/8" hardlines
You're going to need the adapter for the rear cooler line and the spacer. I ended up having the fittings from the SD bypass I tried to install, but didn't have the clearance. I bought the spacers that replace the bypass from Riffraff I believe.
Here is the fitting
Here it is installed by itself
I connected the fitting to the cutback hardline with 3/8" trans cooler hose
Here is the hose/hardline setup
The front connections, by the radiator are straight forward. This was a fairly costly mod/mistake/search for a solution. I hope this helps others out with their OBS T4/E4OD swaps.
I am sure there are other ways that are more robust or cleaner. Hopefully this works!
