Bite the bullet and use stainless. Last year I had an AeroQuip -10 push lock hose come off of an AeroQuip -10 fitting on my oil cooler. The result was a siezed engine. I followed all of the Aero-Quip instructions for building the hose, used all of the correct matching parts and did not use a hose clamp (also per AeroQuip instructions).

The deal is that the push lock hose is rated at 200PSI at 250F. However, you have no idea how hot the oil coming out of an engine is. Eventually the heat must have gotten to the hose on my car. The hose simply came off - no warning - no signs of leakage before the race.

Oh and the guy that sold me a replacement engine for my car......had the same issue on his EP car at Memphis.

I now have all -10 Stainless on my race car and will never use anything else.
