Size of Gas Line

[mowerman]

Hello Again

Thanks for all of your help before. Once again I need your help. I have a 1994 Suzuki 25 HP DT25C. I see a small pin hole leak in on of my gas lines. I plan on replacing all of them now. The one leaking is the one between the fuel filter and fuel pump. Does anyone know what size these lines are? They appear to be all the same on OD size. Thanks once again

Probably 5 or 6MM, never measured them. 1/4" fuel hose may work.
