External oil cooler - fittings, hoses, cooler and more

[red baron]

Hey guys,
I'm currently thinking about what to use for my oiling system for my N/A 2007ccm engine.
Full flow is already prepared with a 3/8" NPT thread in the case.

Now I saw these "new" coolers at lowbugget.com and wanted to ask if anybody has ever used them? I like the idea to order them as a bundle with fan, switch, and mountings - and the price is good.

Parallel to this I'm not to sure about which size of hoses I should use. D08 or D10 for all the lines to cooler, thermostat and filter. Any Advice?
And which size for the breather hoses?

Also I wonder if a hose from the left valve cover to the sump could help to have more oil where it is needed and not just up there. Has anyone tried that and some results?

thanks a lot..

12 mm inside Diameter on hoses. Fittings minimum 9 mm in the throat, preferably 10 - 10,5 mm.

I was thinking about eighter 8An oder 10AN. I think I'll go for the 8AN.

Mabe I use the same size for the breather...
