how big is the hose from the as tank to the carbs, mine broke

Hi,

I think it's 8mm (about 5/16 inch). The OEM part number for your bike is 09343-07026.

Thank you for your indulgence,

BassCliff

EDIT: My mistake. I see that 7mm is the proper size for your bike. The 8mm is used on larger bikes. But that part number is good.

Assuming you're talking about the fuel hose and not the vacuum line, I bought and really like this stuff:

It's a lot like the OEM fuel line, but this guy sells it by the foot. Wonderful to work with, and no clamps required. Got it in just a couple of days going from left to right coast at that...

Great source Mike. Much cheaper than the OE Suzuki line, but looks identical. 7mm is the proper size.

I was using some Goodyear car fuel line for the last couple of years. In that time it had gotten quite hard and was cracking on the outside. I wanted some OEM-style line but didn't want to buy the whole roll, so got 3 feet from that guy and barely used one.

Although clamps are not required, I put one spring clamp on the carb side because I'd really be kicking myself if I had to pull the carbs after I accidentally pulled the fuel line off! I've heard tales told of replacing the fuel line in situ on the carb side by using a coat hanger as a guide.

Auto parts store. 5/16'' fuel line. Get 2 feet and have plenty left over for next time.

Does not fit very well, it's the wrong size.

European car places have 7mm fuel lines.

European car places have 7mm due lines.

Ahh.. didn't look at it being a 550.. Can always get 1/4''. Haven't seen any places that had metric sizing on the fuel lines. Either that or they never mentioned it when I have talked to them.

Why F*** around with thick and stiff automotive fuel hose when you can use thin and flexible line? The auto line requires us of a clamp too, but the thin stuff doesn't.

Mr. BassCliff, much like the bolts used throughout the bike, the size is encoded in the part number.
See the -07 right in the middle? Yep, 7mm line.

And don't be put off by the seemingly high price of about $15 for that line, as you get 6 feet of it, or about $2.50 per foot, like that other guy on eBay.

No, Wrong size.

Still wrong size, the 550 uses 7mm line, too.

Did you not read tkent's post?

Ed, the Euro places still have low pressure tubing, the 7mm low pressure stuff is very good. High pressure stuff from auto zone or whatever is terrible for our purposes.

Did read his post. STILL HAVE NOT SEEN IT ANYWHERE. I haven't seen you being one of the snappy people on here before.

btw, I have 5/16'' on my 850 and it fits perfectly.

Did I happen to point out that I have an 850 and not a 550, hence why I was just suggesting the 5/16s and making a distinction between not noticing that it was a smaller model than mine which frequently causes the manufacturers to install smaller lines.


I did some number crunching and it appears that a 1/4" line can flow up to 20% less than a 7mm line. Not saying that the petcock and fittings and everything can flow that extra amount, but since I did the figures, I wanted to throw it out there. The 7mm line is only .03'' wider though.
