Carb overflow tubing - source & size
« on: December 03, 2008, 08:10:22 AM »
My CB350F didnt have these when i purchsed her.  Luckily, my carbs dont leak, but i'm replacing any bits and pieces which are missing. 

Do you know of a source to order lets say a 4'-5' length, or is there some alternative, which can be used that can withstand time/gasoline? 
...and those little 'omega' shaped retainer clippy things too!

Also, do any of you know the ID and OD of the original tubing?

Thanks in advance

I would think most of that tubing is the same size or pretty close.  Since it is just overflows that do not have gas in them much, I just went to my local hardware store and found it there.  I have seen it on eBay for like a $25 rip-off just to have the Honda label.  I spent like $2 or less.

i think the carb overflow is like 3/8ths..you can get helix lines at like cycle gear or just google helix fuel lines...like 5 bucks for 5 feet... the fuel line is 1/4 inch i believe...you can get it in different colors too....clear, translucent blue, red, yellow etc...

I just took off the float bowl and took it to the hardware store to get the right size.

That is just too easy, lol.
I don't have a motorcycle, sold it ('85 Yamaha Venture Royale).  Haven't had a CB750 for over 40 years.
