'81 Fuel Hose Size?

[OriginalOwner]

1981 GS750E ; I need the fuel line/hose size. So I can buy them generically at my local auto parts store.

Could have sworn I saw them here but now I can't find 'em, looked all over - I actually need ALL fuel tank related hoses:

They are:

Fuel HOSE - Part No: 0934307091

Vaccuum HOSE for petcock: Part No 1368345110

Vent HOSE: Part No 1368347070

Check Partzilla for the PN's. You can order from your local Suzuki dealer also. The OEM fuel line is really excellent. 7mm ID. Much better than line from the auto parts store.

Just beware of buying New Old Stock fuel line.
Had some a few years ago and it fell to bits after less than a year of modern fuel through it. Just lucky it happened in the workshop and not out on the road.

I appreciate your answer but as Grimly stated, the OEM stuff isn't made for ethanol fuel, which in my area, cannot be escaped. And the part number has changed several times over the 44 years since I've owned this bike, which makes me even more wary ordering stock.

The most recent PN looks like: 09352-70104-00B

7mm ID is a good start! Thanks! Still searching this site for the post with all of the hose measurements for my 1981 GS750E.

Much appreciated.

The Suzuki fuel line is fine for common E10 gasoline. You are assuming too much. It's all I use, even on my Kawasaki. And speaking of that, a bunch of guys on KZ Rider are using the Suzuki fuel line after my recommendation, and excellent in-use reviews.

Automotive fuel line comes in inch fractional sizes, and none match the 7mm standard. Also, these lines are thick and fat, designed for high pressure fuel feeds, which our bikes don't use. The Suzuki fuel line is thin and stretchy. You don't need to use a clamp either.

Thank you for that valuable info. Much appreciated!

No, I said beware of NOS, that might have been sitting on a dealer's shelf for 40 years.
There are people who go around hoovering up ancient stocks and sell them on ebay, still in their OEM packets. They look ok, but some of them are not.
