Hello, I need to replace the two hoses circled in the images below. I cannot get the current hoses off without damaging them.

They will certainly be special order through Honda and will take a couple weeks to arrive so I just want to replace with generic tubes. Can anyone supply me with inner dimension measurements for these so I can grab from a local auto parts store? Thanks

PCV tube, marked with a "2"


Throttle body coolant hose, marked with a "7"

 

Just a standard 1/4" ID fuel line will suffice.

 

Are you sure it's 1/4" ID and not 3/8" ID?

 

Could be....I know I got 1/4" to work for the PCV line as that's what I had laying around.

 

If you use fuel line on the coolant line, it will harden like a rock and turn to an almost plastic state. Then vibration will crack it open.

I've seen a few coolant leaks on the s2000..Every one of them was from the coolant bypass line that you install when you do an intake on the car. The line was hard like plastic, and split open because of it.

 

Ah yes, good point. I guess I should clarify that the only one I replaced was the PCV line and for that I used fuel line.
