Dan Marc questions

[HBFL]

The DM .250 is on its way.

Is 5/16 ID fuel line ok on the petcock line and the two carb feed lines?

The carb lines measure out around 3/8 ID.

Thanks in advance!

That's what I used.  along with a brass T coming off the Dan Marc.

I went T on the AFC valve to the carbs and 3/8 hose to the tank which is a loose fit on the pingel, I use a hose clamp that is easy to access with a long screw driver, makes it easy to get the hose on the tank
