Why for you ask this here question young Benny?

AN is a thread standard it does related to a pipe size but does not have to. I have AN6 fittings weld on my 8mm fuel hardlines.

-6 is heaps big enough for fuel, but only use this hose for the dash (speedflow) fittings.

 

If this is just for your normal barb fittings on your carbs and normal fuel line get 1/4 or 3/8 etc

Hey Benny

 

AN refers to the American standard 'Ármy Navy'...hence ÁN'.

 

AN6 refers to 6/16 outside diameter (OD) of the tube. Hence the tube would have an OD of 3/8". The inside diameter (ID) of the tube is not specified under this system, hence the ID can vary depending on the application and material...there is a way of determining this too, depending on material etc. In the case of hose, it can generally be assumed AN6 corresponds to 6/16 (3/8) ID. Obviously the ID of hose is generally set up to match the OD of (metal) tube.

 

AN8 relates to 8/16 or 1/2"diameter, and so on.

 

For fuel, AN6 is plenty.
