Fuel hose - what to use ? any clear that doesn't get hard?

Fuel hose - what to use ? any clear that doesn't get hard?

Also what size? (Even if I order some of what you might recommend to the question above, I need to get some temporary hose for now)

Use genuine Suzuki fuel line. It's 7mm whereas most products that you would get in an auto parts store are either 1/4" or 5/16", one of which is too tight, the other too loose requiring a clamp. One package of the Suzuki fuel line will last you a long, long time - there's about 6' of it.

Beware of old stock Suzuki fuel line.
I thought I'd scored a bargain, but it fell to bits inside a year - split along its length, which would not have been good out on the road. Luckily, it happened during a routine check.
I don't know what it was; whether it wasn't what it claimed to be (but it was in the right package, with the right numbers, and looked unmolested) or modern fuel mixes just proved too much for it - allied with the natural ageing of rubber.
I think I'll score some Tygon line for the next installation.

No need for NOS or special parts, you can ask your local bike shop or hardware store for any length of fuel-resistant hose in the right diameter. (If you take the hardware store route, really make sure through either documentation or asking one of the clerks).

Any clear hose, to my knowledge, will harden (as black one will, but not as much).

When I got some replacement hoses (cut to length from reel) for the vacuum and fuel line, the shop owner made sure to highlight their difference. Apparently they weren't interchangeable.

I prefer OEM fuel line, but whatever you end up with, make sure it is 7mm inside diameter.

The problem with most automotive hoses you might find is that they are reinforced for higher-pressure pumps found in fuel injection systems. There is no need for that. Besides being thicker, they are less pliable and might not make the corners necessary under the tank.

As Skinner mentioned, when you buy a hose, there is about 6 feet (probably 2 meters) in the package, which helps offset the price tag.

Clear hose will...hose you. Tygon is the way to go. Motionpro sells 6' sections in a package that most bike shops carry. Made all the difference in my garage not smelling like the gas leaking past the hardened clear vinyl line.

2x on the Tygon! I think Jetsrus sells it as well.

There are different grades of Tygon tubing. Only one specific type is rated for gasoline.

I ran clear tubing from Home Depot for a few months while sorted out my carbs. It held up quite well, but I replaced it with some proper fuel tubing as soon as I could.

The stuff sold for motorcycle fuel line should be the correct stuff. You can buy anything on the internet, though...no telling what you get sometimes.

I also did the clear tubing for a bit - made a mess. I use it for my carb vent lines now. Seems to reduce the gas odors.

Tygon? F-4040-A is the type rated for gasoline. It's translucent yellow in color.

I picked up 2 feet of 7MM fuel hose from a local shop that specializes in older Volkswagens....carbureted. Cost me a buck...isn't clear...but is new and gasoline rated.....downside is it is made in...er Germany....;-)
