im converting my whole engine bay to aereoquip but the big hose on bottom of the header tank which is big! what size fitting would that be the equivalent? i was thinking -12? obviously this hose goes to the main rad hose to the water pump, how do i get this aeroquipped?? i dont want any jubilee clips anymore

 

I'll send you all the sizes/equivalents, or drop off wednesday after gas man's been, came tonight at 20:45!!
