Hey Guys,

Just wondering if anyone on here knows if anyone's every changed their fuel lines or any other lines (other than brake lines) to stainless steel braided?

I wonder if the race teams do it?

Reasons why I was thinking about doing it:

1. My main fuel line (right under the tank) connected to the fuel pump and routes to the throttle bodies got kinked. So fuel is not efficiently flowing through this line and the bike hiccups like its starving for fuel. I can't imagine how it got kinked so bad, the inside of this line is some sort of hard plastic.

2. The OEM line (P/N#51044-0118) if ever gets messed up again or kinked or damaged... this part is backordered EVERYWHERE. I've checked all online oem parts dealers, all motorcycle dealers around me, and nobody can get it. You have to order it overseas and takes approximately 2-3 weeks to get it, unless you find one used on ebay in which i have not been successful in for the past 2-3 weeks (should've ordered it over seas by now lol). Not sure if this is accuratly true, but I've even called Kawasaki Corporate here in the states and they say Kawasaki generally don't stock oem parts with dealers that they don't think is in high demand (that sucks but it's understandable supply/demand).

3. IF you do SS, you won't have to worry about it getting kinked ever again :badteeth:

Problems i've encountered while trying to find someone to make a Stainless Steel braided fuel line:

1. Checked a couple places around me who do custom SS braided lines for old school cars, diesel trucks, and even big rigs. They all say that they can't because of that special fitting (the connectors are square with the red clips).

I think that's kind of BS, i'm sure someone can make it... just have to find them.

Any ideas???

SS lines look cool, but they are like little bandsaws if you don't completely prevent them from moving or coming in contact with other lines/wires/metal. I've done several set-ups on with socketless hose and fittings, and it works really well (also called Push-Loc and Twist-tite). It's cheaper, easier to use, and lasts just as long.

Scroll down on that thread and there are some picture examples. :) If you were just dead-set on using braided steel you could do exactly the same thing with those hard-line adapters and reusable socket hose AN fittings.

If the SS fuel lines are coated with a plastic sleeve, like most brake lines are, I couldn't see it doing much damage.
On a different route, there is Tygon fuel tubing (the translucent yellow stuff) that is better than rubber. Won't kink as easy, plus it just looks awesome. About $8 a foot though I believe.

I've never seen coated SS lines larger than -3AN, but that would be cool if they made a -6 or -8 coated for sure! Probably freakin' expensive, though.

Also there is the new(er) style nylon braided socket AN hose. Constructed exactly the same as the SS hose, but they use a tough black nylon instead of steel. It looks tits, and it doesn't saw through stuff. :)


Also, Aeroquip makes a socketless type hose that is BAD ASS (also a polymer/non-steel hose). Very tough, high pressure, abrasion resistant stuff here.

This is the adapter that will work with the stock fuel rails... commonly used on GM LT1/LS1 fuel rails.

Anyone here know the inner diameter of the oem rubber fuel lines on the 4th gen??
Would think they'd be the same on all the gens, but don't want to make an assumption.

Those top links are garbage worm clamp style fittings and hoses... You couldn't pay me to put that on a vehicle. Most of the other links are just plain old uncoated braided hoses or low psi fuel hose (carb stuff). I didn't see anything in the -6 or larger range coated. :dontknow:

Didn't really look into it that much. Was looking for something else and came across it so I posted it in case it could help.

Summit Racing & Ebay are your friends for finding AN fittings and hose, hands down.

Wow, I am appreciating all the responses on this thread.

Here's an update with what happened with my fuel line problem:

1. Luckily King's Garage in Garden Grove, CA had an extra OEM one for me to use.
2. I held up the one i got and the one that was on my bike. (I'll take a picture of the my oem kinked one, and try to post it to show the difference between the oem one Kings Garage gave me) You can tell there was a slight kink in my hose... looks like maybe i didn't make sure the hose was clear before setting the tank down or properly angled before setting the tank back down.
3. I put the new fuel line in and made sure everything was clear of it, slowly setting down the tank until i couldnt see the line anymore.
4. Took the bike out for Motoyard track days at Streets of Willow and Big Willow this whole labor day weekend... NO problems. ALL the powercommander stuff worked flawlessly and the bike wasn't hiccuping seeming like it was starving of fuel.

Some things to think about:
1. I didn't think the fuel line could actually kink like that? The inside of the fuel line seems to be of some hard plastic or i thought it was tygon?
2. Lesson here is to make sure the fuel line is clear of everything (when lowering down the tank after working on the bike) and isn't kinked or smashed up against anything like PC stuff or any other extra accessories you decide to put underneathe the tank. I guess that is common sense though :2bitchslap:

Yeah that is a common issue. Just have to make sure you pull the slack out of the line when setting the tank back down, keeping an eye on it on the way down. It'll try to kink on you (usually up at the tank) every time if you don't. It's a habit for me to double check it whenever I mess with the tank.

You just push both plastic clips in and pull it off, though a twisting motion helps break it free. It's just like some types of automoive fuel filter. Honestly, if I need to take mine off I just unscrew the fitting at the AN flare... takes me less time/finger pressure. :)
