Fuel line size

[Red Hatt]

I wanted to order the vetus fuel anti siphon part. I'm not at the boat and i don't know the fuel line size. I do know the fuel cap is 2 iches so would that make the hose size 1 1/2 ??? Its a 46 Hatteras.

2" pipe is roughly 2 3/8" outside diameter for hose. Not sure I understand your question though.

I replaced all the fill hoses on my 46 c, hose size is 1 3/4
