Anyone...........?

 

I googled this and did a search but didn't come up with anything. I do however remember seeing a thread with this exact answer but can't find it so I know someone out there knows.


thanks

 

I asked this last fall. One of the more knowledgeable guys here said there are three sizes. I bought bulk rolls of those sizes and I have them in the garage at home. This will be one of my spring projects.

I will check this afternoon and let you know

 

That thread is right here, to give the man his due credit

thanks for the reply to both DZRick & brdd. That's will be great, I can figure out which colour is what size.

 

The sizes and colors are found on this site Frank, under vacuum hoses.

Are the sizes listed here ID or OD or does the OD matter?

 

nevermind I found it in the other post

 

Hi there
I'm after the exact diameter of the green hose from actuator to relay valve. All I find is the length size.
Thanks
Simon

 

This thread is six years old. The diameter of your green hose is likely to be the same as the red.

 

Hi Mike

Thanks for your reply but I'm still after the diameter of the green hose and now the red hose. When I search for the sizing I'm unable to find the answer anywhere.
Thanks
Simon

 

I'm lost. Inside diameter or outside diameter? If you have an original piece of the hose remaining, measure both. If you are replacing all the hoses, order a kit.
