well look at the newer sled like the 2014 800 rr has newer material for hoses an its gray and don't for get to buy the clamps for the hose end

 

For lines constantly submerged in gas like that, you need a special type of line. IMO, unless you buy them from the dealer or you buy line made especially for constant immersion in fuel, keep the factory lines in it.

 

I was just gonna swap out the lines that run from the top of the tank down to the throttle bodies. Maybe I'll just leave the stockers on there.

 

you can replace them, if that's what you want to do.

you just have to make sure you get FUEL line.

there is not a clear hose that's rated for fuel. it will be blue or yellowy orangeish.

if you have throttle bodies, I assume its efi. if its efi, you need fuel line rated for the pressure. the blue or yellowy orangish are not going to be rated for what you need. they will work, but will swell much faster because there not reinforced.

a fuel line that's swollen is much more prone to bursting.

you can go to your local auto parts store, get some efi fuel line for a car, its rated for 300 psi which is way more than you need, reinforced rubber, and available by the foot. you should be able to replace all your fuel lines on your sled for $10.

it should also be noted, that line rated for fuel does not mean its rated for oil. you will want to check on that if your considering replacing your fuel line and your oil line..

remove the fuel line from the sled, and either cut a 1" section off and take it with you and hand it to the parts guy and go I need this, or take the whole fuel line.

and if your taking the time to replace those lines, its well worth the time to replace all the line in the tank as well. that line generally goes bad before the line(s) in the engine compartment.

 

Also with all the ethanol in today's gasoline make sure you get a fuel line that is ethanol resistant. Ethanol will break down the rubber. It all "Should be" resistant nowadays but never no if you end up with older line or cheap line.

I had to replace all the fuel lines on my boat due to ethanol break down.

Now I look for ethanol free gas. Yes generally its always 91 octane or higher so more costly but worth it in my book!

 

As far as the size of the hose, Just buy the same size that came off of there. I just go into my local dealer and they sell the good stuff at a price per foot. Its not very expensive.

 

I figured you meant the lines inside the tank, opsie! As mentioned above, if you have EFI make sure to replace the lines with fuel injected rated hose. This isn't so critical for the return on certain sleds, but it's still not a bad idea to use the high pressure stuff. Size, usually it's 5/16" for feed and 1/4 for return, don't quote me on that though.
