Replace Brake and Fuel Lines Every 4 years?

[barry]

Service intervals show to replace brake and fuel lines every 4 years. I have an 02, lines never changed (that I know of) and the dealer says they look good.   Should I change them anyway? Anyone have a fuel or brake line failure due to age? I'm all about preventative maintenance but don't have money to burn either. What about steel braided lines? Wouldn't the service interval be longer?  How much is the average for the dealer to replace fuel/brake lines?

get a haynes manual ( or clymer), fuel lines can be done one at a time to make easier. stainless braided. i believe ( unless im wrong) have that covering over the line material. but if they look good, i might still be tempted to do it.

I check mine a couple time thru the season.I only change them if they are chafed,cracking,dry rot,getting to soft or to stiff.I use 8mm and 10mm tygon when I can find it cheap.

I have bikes with 35+ year old brake lines with no problems...I have bikes with 2+ year old fuel lines that leak like sieves.  Fuel lines I'm eager to replace....they're cheap and simple.  Brake lines I carefully inspect on a frequent and regular basis, but I don't stay awake at night thinking about them.

Mak,do you have an online source for thin wall fuel line?I'm having a problem with standard auto fuel line and I can't get tygon locally anymore.My online source doesn't currently have it and don't know when or if they'll get any more.Besides clear fuel lines look outta place on an all black bike.

Always eBay.

depends completely on environment and usage - temperature fluctuations, humitidy, sunlight, etc etc replace them if they need to be. if they are cracking, thats when you know somethings up, or if your brakes give out and you die, or you catch on fire, and die, those are some other signs.

That's where I was getting the tygon online but the guy says he dunno when or if he'll get any more.  The other places I tried only sell in bulk.I'll never use 50 feet of tygon.

buy the spool, then start a conspiracy about fuel lines rupturing, sell it at cost + 5% per gs member

Try these guys for fuel line and some other parts.

http://crc2onlinecatalog.com/

They specialize in parts for older bikes, but have some things for the GS500's, like shims, carb kits, brake cylinder kits, gasket kits, and some engine parts.

Thanks Mak.I didn't realize that was a link to the tygon I needed.I'm a little off still from the Flu.

Just so happens replacing the fuel lines is on my list of things to do in the very near future. You mentioned 8mm and 10mm lines. I can't seem to find the metric measurements online anywhere, everything is standard. So, what size do I need? I've seen 5/16" and 1/4" both mentioned on various forums. Any help would be appreciated. Thanks.

I can't remember right off but one of the petcocks(or is that carbs?) is a little bigger than the rest of the fittings.1/4 is the best size,a little hard to get on.Don't need hose clamps with 1/4.5/16 is ok but I'd use small squeeze type clamps.To me they are easier to remove while balancing the fuel tank on the edge of the frame.

Wouldn't any 5/16" polyurethane line do? They sell them pretty much any auto store?!?

Raising the dead...but I was looking for sources of fuel lines for my bike and came across this thread.  Thanks for the sources.

I was taught to use Vaseline on the external surfaces of fuel lines by a guy that restored old cars.  Lines don't seem to deteriorate as quickly or be as susceptible to dry rotting and sun damage.

And bringing it back up again - anyone have any spare line that they bought in bulk and want to sell off?
