Yanmar 3GM fuel line size

[py26129]

Shortly, I will be replacing the fuel line from the tank to the engine. The boat is equipped with a Yanmar 3GMF (Very similar to 3GM30)

Does anyone know what size fuel line is used with these engines?

I checked andd was not able to find anyhting re size printed on the existing line but would like to buy before I remove the old line in order to preserve sailing time.

Many thanks in advance

Mine had 1/4" originally. I just upgraded it all to 5/16" because that is what my Racor filter barbs were and I got tired of trying to stretch the hose onto the filter. I had to change the one fitting at the fuel tank dip tube.

5/16

5/16 is what I put on my 3GM. I believe it was 1/4 originally.
