So after a deep deep cleaning and covering the front of the engine in baby powder I believe I've finally found the source of my oil leak.
I believe it's the fitting between the hard line and the flex lines for the oil cooler.
Are there any O-rings or is that just a compression fitting?
Where they sit there's no way for me to get them any tighter, I just can't get the leverage on the wrenches to get any tighter than they already are.
Does anyone make full replacement lines from the oil filter adapter to the radiator? preferably without the extra fittings in the middle (the ones that are leaking)

J.R.'s are first rate. And they route a bit differently than stock. I think
for the better. But, opinions vary.

J.R's are first rate and unbreakable. Guaranteed forever. Just be sure you get the right one for your block. 403 & 455 are different. Also, the oil filter adapter is different for each engine.

I'd just rather have a single length of flexible line if possible
The JR stainless flexible lines for the GMC with 403 engine are single piece flexible from the oil filter adapter on the engine all the way to the radiator oil cooler.
Just order 403 ones from JR or Jim K.

You may be able to get by with a couple of copper flair washers between the hard steel lines and the flex lines. You are using stainless Teflon lines and not the original fabric lines? If not you need to get JR's lines.
