external oil cooler line size?

[scojack_2001]

Guys, I need to know what size -AN line to run for my external oil cooler. I run a IROC radiator and took the oil cooler off when I did the TC. The old lines were high pressure rubber hose, but they were too long and hung low.

I was told -10, but wanted to be sure. Also planning on doing the big oil filter conversion as well.

Thanks in advance.

I use -8

as thats the size of my oil cooler, and I believe thats the factory size also,
,but maybe some one will know for sure,

-8 will work fine.

Thanks guys. I guess I'll go with -8 (5/8"?) since I'll save some money and a little weight.

Would there be any noticable difference in pressure?
