Yes, if you don't get a good straight cut on the hose sometimes you need to use a knife to clean it up. On the aluminum fittings I use anti-sieze, but I'm sure motor oil will work OK .1 thing I can add is that after cutting the line, I suggest deburring the edge of the teflon with a razor knife. It allows the Ferrule (olive) to seat better on the end of the line.
They also make aluminum hose ends. If using these I recommend motor oil on the threads to prevent galling.
Good looking engine you have there Neophyte .Awesome write up!! I used a the same hose for fuel lines on a DD453 I rebuilt over the winter. The critical part was cutting the braided hose with a fiber cut off wheel (took a couple tries to figure out that was the best method). Once the braid comes undone.....impossible to connect the compression fitting on.

They are the "cats meow ! " I see you used the aluminum fittings. I always just use the steel ones, that way I can recycle them to use on hydraulic systems if I need to.Thank you. I wish this write up was available 6 months ago.......I must of cut the braided hose 4 times before getting it right. I used 8an fittings throughout the fuel system...worked like a charm. These PTFE hoses are a huge step up from the old rubber hoses.
