This is our 90 degree fuel fitting kit, so that your fuel line routes out the bottom of your gas tank in a safe, rearward fashion.
This part fits all aftermarket (and oversize) fuel tanks, and flows more fuel than the 90-Degree Tank Fittings that come stock on the 2017 fuel tanks.
So using it is win-win-win. Be safer, flow more fuel so no leaning out when at higher rpm's, and fits all tanks if you get an oversize one in the future.
The stock tank fitting on 2012-16 bikes is on the left, below. It's easy to see how a branch could rip your fuel line off or slice it. And since it's under high pressure from the fuel pump, you don't just duct tape it and get home.
Our 90-Degree on the same tank, on the right below, is an even lower profile than the stock 2017 fittings and gives you the safest fuel line routing possible.
I understand why you wouldn't think you need this on your 2017, as it already has a 90-Degree, but there are 2 good reasons:
One, even if you never get an oversize tank, the stock one is more restrictive than this one and causes the bike to start leaning out, as witnessed on the Air/Fuel ratio meter, when pinned in 4th gear on the 350 and 450, breaking the law around the hard core streets of Paradise Valley, Arizona.
And two, it will fit your oversize tank if you ever get one.
