GT750 L/M/A/B Fuel Line Diameter?

Post by RING_DING »

Maybe this has been posted somewhere already, but I can't find it! What is the Internal Diameter of the fuel line from petcock to carb (single line on LMAB models)? I'm thinking it's 1/4 inch, but would like to know for sure.

I believe it is 8mm, which would make 5/16" very close.

Thanks Conner, but I think I have just answered my own question. On the parts fiche the fuel line is 7 x 10 (7mm inner x 10mm outer diameter). I picked up some genuine Suzuki 7 x 10 from my local dealer today.

I may have been looking at the wrong model, was looking at the parts listing here: http://www.powersportspro.com/pages/OemParts#

That's where I came up with the 8mm (I knew it was a metric sized line).

Check out #15 here:

It's a bit confusing because #'s 12, 13 & 14 are for the prior J/K models that had the three separate fuel lines and they are smaller (5 x 8mm)

Yes, that's the page I was looking at.

But then, I have a T500. What do I know about water buffaloes? :wink:
