Does anyone know the fuel line size for a 1983 GS750E, couldn't find it in the service manual and dealer had no idea.

Thanks

The internal diameter is 6.5MM. The OEM hose is the only one I've ever used that didn't require a clamp to keep it from leaking. They come in 600mm lengths (almost 24 inches) so you'll get enough for several uses.

The order number is 09354-65113-600. I think you'll find that your local dealer "has no idea" about a lot of things.

Actually, it's 7.0mm internal diameter and the part number is 09352-70103-00B

You can find it on the FUEL COCK fiche, but it's listed as HOSE, WATER DRAIN.

That's weird, I wonder why it's called a "water drain"??

[Steve]

Same hose is used in multiple applications. Might be the drain for the airbox on another model.

I looked up the part number, that's what I ordered last year when I needed fuel line for another bike.

Like chuckycheese said, though, it's the proper size (even though he listed another size) and you don't really need to clamp it to the petcock or the carbs for a leak-free fitting.

Thanks, I will order.

Hose

I've got a couple of extra sets of carbs and several OEM gas lines and I measured all of them. They were the same and all were 6.5mm or very slightly bigger (stretch factor). All were well under 7mm.
The ring on the nipple of the petcock is 9mm so I feel sure either a 6.5mm or a 7mm would be OK. If I were going to order one I'd opt for the 6.5mm hose. It will fit slightly tighter....and it's cheaper.
