79 GS 850 g fuel line diameter

[Guest]

Hello everyone. This is my first time posting here. I've been pulling my hair out trying to find out what size hose my 79 GS850 fuel line requires. I work in an auto parts Warehouse that has a full lineup of Gates hoses. I really don't want to spend the $20 to buy the OE part when I could get the stuff for pennies at my job. Any help on the matter would be greatly appreciated. Thank you all and have a wonderful day!

All of the fuel lines are 7mm

If you want to find it locally, look at a foreign car dealer, because I'll bet that all of the hoses that you sell are probably in INCH sizes.

The proper size is 7mm, as cowboyup said. 1/4" hose is 6.25mm, 5/16" hose is right at 8mm. And virtually any hose you sell is reinforced to withstand high pressure in a fuel injected engine. All that reinforcement makes it thicker and harder to run where it needs to go.

If it's any consolation, fuel hose part number 09352-70103-00B is only $13.20 from Parts Outlaw. To make things even better, you should know that you get about six feet of hose for that price. One last deal sweetener: when you get to the checkout window, enter the word "BANG" in the promo box, shipping will only be $1.00.

Thank you very much. We do carry metric fuel lines. I'm going to see how thick they are compared to what's on the bike and go from there. I may end up just going to a Suzuki shop and see if they'd be willing to cut me 2 feet of line. If nothing else pans out I will definitely be using the link. They seem to have a lot of other things that I will be needing. Stuff like coil packs, points, brake lines and possibly a caliper rebuild kit. I'm going to check the condition of all those things before I replace them of course. Thank you all again for your assistance in this matter.

My GS850 has been wearing 5/16" line for, oh, about 20 years...

I keep meaning to buy some of the Real Stuff, I really do.

Be conscious of quality if you buy 7mm line. I'm guessing that like most stuff you get what you pay for. I bought some off ebay and it rotted and split in one season. I run only non ethanol premium in my GS850 for octane reasons. It rotted on my Guzzi with ethanol as well (Guzzi is not octane sensitive). So it wasn't a gasoline type thing. I don't remember who made the more expensive stuff I used to replace it, but no problems since.
