Yanmar 1GM10 Fuel Line Diameter?

[sailingjupiter]

I'm looking to replace the fuel lines from tank to engine on my Yanmar 1GM10. Boat isn't local to me so does anyone know the internal fuel hose size I should be after? I have measured the distance but thought the diameter would be in the manual but can't see reference to it. I assume all 1GM10's are the same?

I have seen ASAP selling 6.5mm but also a local chandlers selling 5mm (internal diameter). My history of accurate measurement would say I would get it wrong anyway!

Have used the search here but can only find reference to the same question for the 2GM10. I assume they will be different.

Many thanks.

You should find the answer buried in here: http://tinyurl.com/y9dt5yg (http://www.motoren.ath.cx/menus/yanmar.html)

I would expect 1GM10 and 2GM20 parts to be the same.
