Fuel Vent Hose Size on Californian 42LRC?

[Montenido]

Hi folks,

I am looking to add some of the fuel vent whistle devices to my boat, but I can't seem to find any marking on the vent lines to tell me the size of hose. Do any of you happen to know the stock size for the fuel tank vent lines? 1979 Californian 42LRC.

Here is the item that I wish to install: https://shop.hamiltonmarine.com/pro...kQ6m4arXZRYaar2COAEzg7Gd-u8HuxIBWMRoCmW7w_wcB

Thanks, Bill

Interesting device. If it works, I would love something like this (I don't own a Californian). You may want to check out Defender. Same device, cheaper, and includes the clamps apparently.

I installed these on my 34 LRC, but do not remember the size. No matter though because your boat could be different. Have you tried to remove one end of the hose and measure it?

The vent line is 5/8 inch, same as the fuel line.
