VM Vac Line sizes, Dealer or Make your own?

[promking]

For the VM carbs, looking for the vacuum line sizes. I have my current hoses but they are all stiff. They all look about the same size to me, but it's hardto tell because mine are all cracked, and stiff. Did you guys make your own or buy dealer replacements?

I need 46 x 2 + 47 (1) + 48 + 49

Thanks.

Have never had to buy the hoses between the carbs (your #47) and I don't know what the specs are on the drain hoses (your #46).
However, before you get #48 and #49, be aware that you get 600mm of hose with either one, which is probably more than you need to do both of them.

OEM is always the way to go as opposed to aftermarket that goes hard and does not fit properly.
As Steve said, if you buy the OEM stuff, you get a whack of it, so maybe someone here on the board has extra in the garage after replacing thiers, Put a plea out cap in hand and they can help you out for the the price of the shipping and a few bucks.

Vacuum lines are 3/16" inside diameter. Fuel lines are 1/4" inside diameter. Any auto parts store should have 3/16'' rubber vacuum line on hand.

Yep, that's what I did. Make sure you specify that you need FUEL line for the 1/4" ID hose. The other stuff will melt.

I use 5/16" fuel hose for the fuel and screw clamps..
Why would you want to restrict a gravity fed system?

4mm silicon vacuum line works very well, and seems to last longer than the standard lines. That's what I have been using to balance 1/4 and 2/3 hanging under the short carb sync tubes I have them attached to, behind the cylinder jugs. If they survive there they will work anywhere.
