Vacuum Pipe

[AndyN01]

Hi all.

Looking at replacing all the vacuum pipes on my diesel 75 Tourer after reading about some hairy issues if/when one splits.

Looking for guidance/confirmation on:

Internal Diameter: 3mm?

External Diameter: 6mm? 7mm?

Length needed to replace all the hoses? 3m? 4m? 5m?

What is "Type 2" or "Type 3" (something to do with fuel hoses rather than vacuum ones?) and do I need a particular one?

What is "Shore A Hardness" ?


Anything else to be aware of such as different sizes in various places etc.

Supplier?


Thanks in advance.

I can't help with sizes, Andy, but I learned a long time ago with my bikes to not bother replacing with new vacuum hose. Rather, I buy bulk fuel hose for vacuum. It is much more durable in the hostile underhood environment. I also use small zip ties around the hose ends if they are not already stretched tight when pushed on. This is when there is a difference between a 3/16" and 4 mm or 1/4" and 6 mm, for example.

Cheers,

Hi Andy.
Purchase your self a few meters of this below, it will not break the bank, also some fitting are better with 3.5 others 4.0 so both is a good idea
