    A Special Note about Email accounts!
    DO NOT SIGN UP USING hotmail, outlook, gmx, sbcglobal, att, bellsouth or email.com. They delete our forum signup emails.

    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

  • Returning Visitors

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

Am going to the autoparts store to look for some hose for my project. I believe the vacuum hose is 4.5mm, the fuel hose is 7mm and the crankcase breather hose is 12mm (not real sure on this). In any case, I doubt the autoparts store will carry small diameter metric although they may carry small diameter inch size. What size hose do you folks use for these applications?
 
Take the metric diameter, and multiply by .03937 to get the SAE size.

Example for 7mm tubing: 7 X .03937 = .27559, which is close to 9/32" (.28125")

4.5mm = .177165", which is ~5/32" (.15625")

12mm = .47244", which is ~15/32" (.46875")

You should be able to find metric tubing locally, especially from auto dealerships or motorcycle shops. If not, it's easily found online.
