The leaking or weeping at the hose and braid says to me that the hose is not properly installed on the fitting (cut straight) piece of braid has overlapped the hose end or has a bend to close to the fitting that it has distorted the shape of the hose on the fitting and for me I think that that the latter is the main problem with hoses popping off. Aluminum fittings can be over torqued and strip the threads unlike stainless. Snug up the fitting and take 1/4 final turn....Check your routing and clamping make sure that the bends are not severe.

One (Tardcore) has bown apart already. They should not leak at the braid. This may indicate they were not assembled correctly. You can take them apart and check but it's awkward to do on the car. Stainless lines have a very high pressure rating normally but if not fully seated in the sockets this could be reduced significantly and potentially leak..

I too am worried as I purchased the GTM kit from Tardcore. However, the vendor replaced the suspect hose (with a much too long one at that). I need to confirm with Tardcore that he did not alter the lines, and that they were directly from the vendor .. that may give me a bit more piece of mind.

Lets move on guys we are beating this one to death.

I suspect Tardcores's were pulled off due to no slack, but this may indicate a more serious problem with the hose assembly. If they are both leaking, both the old hose and the new, I would be doubly concerned. Until you can check them, I would keep my eyes glued to the oil pressure light. Correct assembly is outlined at the end of this .PDF:

These are re-usable fittings, so you may disassemble to check as mentioned above. It is critical that the hose goes all the way into the socket and is not pushed out when the nipple is tightened.
