Lower rad hose???

I'm buiding my first hot rod and find myself asking lots of questions. I've decided to throw this one out there to see who's come across this before and what to do. I've installed the Speedy straight axle kit with 4" drop and am going to run 32" tall skins up front. So what's the question then... Can you run the lower rad hose under the straight axle or must it go over the front cross member? Now everything tells me I should try to go over for the obvious reasons but with the tall wheels it looks like the down under path could work.
If I build a pipe to come over the axle and back down to the water pump am I just asking for air lock problems?

Thanks for your help

 

welcome

 

Welcome to the hamb from st louis....as far as the hose put the radiator on and see where the hose needs to be...but I would keep it up out of the way.....
