I'm looking at getting some AN fittings and braided hose for the plumbing on my 190e 5.6 swap project. So I'm wondering what you all think about sizing. What I need to find is:

1) AN size for fuel hose, power steering fluid hose, and transmission oil cooler hose.

2) Anyone know offhand what the thread size is for the connectors of these circuits? I think the fuel lines at least have 12mmx1.5 fittings, but I'm not sure about the others and I need to order adapters.

Thanks in advance for any help!

If you goiging to use some stock lines (8mm) too wich is easy make up to 600hp then you can use AN6. Stock fittings are M14 and AN6 is 9/16-18 UNF and the hose is 8,75 x 13,89

For transmission oil you can use AN8 or AN10

Awesome, just what I needed! Are both fuel line fittings the same (send and return)? Also, do you know what size the radiator trans oil cooler fittings are? Also, what do you mean by the hose is 8.75 x 13.89? Thanks!

Did you ever get this complete? I'm trying to do the same thing with my Transmission Coolant lines as they need replaced anyway. But i'm still now sure what size fittings I should get.
