Upper Rad Hose diameter?

[Prime]

Does anyone know the hose diameter of the upper rad hose? Looking for an inline tap for temp sensors to go in the hose. Need the diameter to make sure I'm looking at the right one.

if you find one post up. I would like to use an inline temp sensor for mine when I get around to sticking my efan in the truck. Once day I will stop being lazy and work on it.

38MM, I just installed it on my truck for the efan. Link below.

Nice. That's cheaper than the one I was looking at
