Fuel rail plumbing radius

I am designing my EFI system and am making my fuel lines from stainless. I would like to know what the minimum bend radius is (how tight they can be bent) before you start running into significant cavitation problems in the fuel system. This is a V8 with a fuel rail on each side of the intake that will be joined in the front at the regulator.

I've never heard of bends so tight they caused cavitation, and I've seen fuel systems that used fittings that had an unradiused 90 degree bend before. Even if you could somehow put a 3/4" radius bend in 3/8" tubing, as long as you didn't crush the tube it probably would not be a factor.

Thanks Matt, that answers my question. I have just heard some people have run into problems so i thought i would ask.
