this is the hose in question

Okay, 8276 does not run under the manifold. That's the engine air bleed hose. It goes from the top of the cross over pipe assembly to the top of the degas bottle. (It can be replaced with cut-to-length hose.)

3W4Z-8548-AD is a throttle body heater hose. It runs from the water outlet on the top of the block to the throttle body. I had an issue with this hose on one of mine (it was cracked where it bent, almost all the way through). I had to remove the intake manifold (be sure to other manifold gaskets) to replace mine. Someone here did claim they were able to do it without removing the manifold. (Removing the manifold is not as difficult as it may sound.)

You are showing three different hoses. Give me a minute to get part numbers for the other two.

It's the one thats directly under the intake manifold and in the other picture it's the one with the u bend in it

The red arrow points to 3W4Z-8548-AD (throttle body heater hose, from top of block (under manifold to throttle body port)




The blue arrow points to 3W4Z-8276-CB, engine air bleed hose (cross over tube to degas bottle)

The green arrow points to the other throttle body heater hose (from crossover tube to the other throttle body port) I am having trouble getting the full part number, but the partial is 8548C

this is the one. It's split right before it goes into the manifold
