Default engine oil cooler lines

I was wondering if the lines I can buy at the parts store will last any time at all. I think my lines are leaking at the crimp there the rubber hose starts. Somewhere I thought I read on here that the new ones are not much better as far as leaking. They were not easy to get out so I would like to do this only once.

i was looking around to do the same thing,and i think i might end up making my own. i found a place called lubrication specialist and they have a kit. some of the sponsors here might a kit also,but i haven't gotten that far. i also read somewhere that you can cut off the crimped part and put a flare on the metal part and slip the hose with 2 clamps on each end.i might go this route for now.

I just took them apart and put new hose in them with double clamps at each end got that idea from ricansdiesel . started and ran for about twenty minutes no leaks have not run down road yet more pressure may make it leak ?? well see

I have the same problem, I'm gonna take them to a local hydraulic shop and get new made. It really is a bad design by chevy to seal them up the way they do. My Hydraulic shop is going to make them like a O-ring sealed hyraulic fitting, the oring seals on the out side on flange of fitting. May cost more but garaunteed to never leak.
