When I put my air locker in the ring gear messed up the copper air line. Anyway I ordered a new one and it looks a bit different and a little smaller diameter copper airline possibly. Does anyone know if this will work as a replacement? If not, where to find the correct one. (Order the new black one in color from marlin crawler)

 

Quite possible what you got was boxed wrong or ordered wrong

Do the numbers match with what you ordered ??

If it is the wrong size it is not going to work

this website lists different seal housing for different differentials. There must be an ID the housing?
