I took my tank off to work on some stuff.
I disconnected the 2 "quick disconnects" hoses from the tank and forgot which one goes where.
Does it matter?
If so are they marked?

Attach the fuel hoses (18) and (19) to the clips (16).
That what it says..
Yes but they are indistinguishable which leads me to think that it doesnt matter which one goes where.
Screw it I'm going "eeny meeny miney mo".
I know there wont be catastrophic failure but I just dint want to have to pull the tank off again it its not running right.
Trial and error
Fyi it does matter
It was a 50 50 and I got it wrong
(Or at least I hope thats why its not starting)
Could it be the battery?
Best check with spikec.
*chuckle* Butt serially,it probably doesn't matter how you hook them up, because the factory only puts 2 on so that they can sell more hoses. Just put a t fitting in there, hook both hoses together and plug the extra tube.

And if its not that, whatever the problem, it can usually be fixed with a modified beer can
You guys/gals are such a big help

I switched them and it started.
Still not convinced that it matters
The way the fuel system works is a fuel loop. The feed goes from the pump to the throttle bodies and excess is returned to the fuel tank. There may be a check valve in there to keep fuel from flowing backwards, which would come into play if it were connected backwards.
On all the plastic tanked bike the fuel pressure regulator is in the tank.
On the earlier steel tanked bikes it was mounted on the throttle bodies.
It is a one way device...fuel from the pump to the injectors and return through the regulator.
So it does matter.
You would think they would mark them "d/s" or "l/r" but no. If the dumbass is too dumb to mark them when he takes the tank off then were going to make sure he has a hard time figuring out which one goes where.
Ok im done.
As always thanks Nate.
They used to mark them with a plastic ring.
M for mandata/delivery and R for retourno/return.
As the owners manual always says, "see your dealer" not matter what! If they marked the hoses, you wouldn't need to see your dealer, now would you?
****new problem****
HELP
i thought the bike was starting but it sputters after about 5 seconds and dies.
So I've reversed the fuel lines and had the same problem.
the new thing i've noticed is when i turn on the ignition the fuel pump sounds VERY different.
in stead of sounding like Zzzrrrrrrrrrrrrrr like it usually sounds, it makes a louder SSSSHHHHHHHHHHh sound (it made this sound with the fuel lines switched around both ways)
I can post a video later but the bike is obviously not getting fuel and will start only for a while with the residual fuel in the lines.
There is nothing more depressing than not being able to start your bike and not knowing why, and I'm kicking myself because if only I had taken 2 seconds to mark the lines.
working with the tank on the new gen monsters is a PITA (no kickstand) and sharp metal under sides which makes this soooo much more annoying.
Thanks for any input/opinion.
Are ya sure there's enough fuel in the tank? Mine makes a very different noise when the fuel level is below the pickup.
Trying my best to not be offended here.
Yes the tank is half full/empty
Dude, it's something else. I'm almost 100% sure it doesn't matter how the hoses are hooked up on the new bikes. They're an open loop. I have about 30 throttle bodies on a pallet I bought off eBay for TPS and injector research...

An loop is what I'm thinking.
Maybe its a kinked hose or a bad connection on the quick disconnects?

What did you do when you had the tank off?
Did you go inside?
No. Did not disassemble anything in the pump or tank. Only disconnected the quick disconnects.
(I was wrapping my exhaust and wanted more room to work with) why I removed the tank.
I have limited experience with q/d's.
Usually they leak if you don't get it right. My tech advises lubing the o-ring on reassembly to avoid tearing.
I always re-trace my steps if all of a sudden something I messed with doesn't work anymore.
BTW...sorry about the earlier misinformation about the lines. I was basing it off the early bikes.
Battery?
Ive never considered anything on this board misinformation.
It js a godsend.
I'll try to take the tank of Yet Again and do a better inspection.
+1 to lubing the QD o-rings. I always add grease to them. The only times they've torn for me is when I haven't added grease. :P That's part of why we sell those now. Plus ours are Viton. Ducati (and most manufacturers) are not super aggro about using Viton for sealing rings. Viton has about 100 degrees superior temperature range and much longer resistance to fuel than plain BUNA o-rings.
I'll be buying some from you today chris
So what is your problem? Gas leak? Or poor pump work?
How does light work? Is your battery ok? Pump sounds bad when battery discharged. Also M696 can give HI BATT error on low battery.
I found the issue:
(http://i379.photobucket.com/albums/oo240/jessethibodaux/20130721_094852-1_zps8f70d972.jpg)
this kink was hiding under one of the tags/labels on one of the fuel line. I temporarily fixed the kink, put the tank on, attached the quick connects and bike started but sputtered and shut off.
I then swithced the in/out fuel lines and the bike STARTED :D and ran for 10 minutes with no problem.
I believe our suspicions were correct. DP was correct and there was no "mis-information" given. As for my experience, the fule lines can not be switched. However I still don't see anyting identifying on the lines which one goes where. The pump itself is labeled "in" and "out" though.
Its always the most simple things.................
I knew it wasn't: Gas leak, fuel pump, the light?, the battery, or a poor connection on the connections. the problem was so simple I didn't even consider it (also it was hiding in a pretty good spot so I don't feel so bad).
a quick note about these fuel lines on the new gen monsters (I'm not sure if they are the same on the older ones)
they are obviously prone to kinking, so beware when taking the tank off.
They're made of a more stiff plasticky material different from the ones I've seen. I have always seen fuel lines be the more rubbery type and have never seen them kink like this.
I might be replacing the stiffer hoses with the more common rubbery ones. Does anyone see this being a problem?
I'm so releived. [drink]
OK, this is one where I did NOT think it was the battery!
Winner winner chikky dinner
Serially spike,
Not sure why everyone thought battery when I clearly stated that the bike started and ran for a few seconds..
Either way. Its running now. Thank the magic man in the sky.

I do... we add a little bit of fuel line to the pumps we sell for various bikes and I trust only one fuel line currently available. It's the braided shiny stuff from Helix racing (http://www.parts-unlimited.com/products/?productId=132375&partNumber=07060191). I've had a few long chats with the owner-guy there. They do colors and we are buying all of their spools of "not red" defect hose for our application. It's kinda pink. The Parts Unlimited link I put in is for clear. Any good local shop should have this stuff.
:) Chris
Thanks for the info chris.
OK I'm officially closing this thread unless anyone has any more insight.
Since my starting issues, I have:
-Replaced sparkplugs
-Replaced Fuel lines
-Checked EVERY mother freaking connection
-Switched in/out fuel lines (this turned out to be the problem but not for the reason you would think)
-Replaced QuickDisconnect O-rings (Thanks Chris at CA Cycleworks for getting them to me fast, I really appreciate you guys)
None of this worked until I decided to look inside the tank.
The culprit turned out to be (and I am 100% sure that this is the issue):
(http://i379.photobucket.com/albums/oo240/jessethibodaux/20130727_170125_zpse7631f7c.jpg)
To Chris' idea of the fuel system being a "closed loop", you may be right (I still haven't verified this and will not). It may not matter if you switch around the fuel lines, HOWEVER, once you switch them, you are shooting fuel through hoses one direction that used to flow in a different direction. What does this do? This loosens debris and sends it to the (you guessed it) FUEL FILTER.
Remember that PSHHHHHHHHHH sound instead of the ZZZRRRRRRRR sound that I mention that was a new sound when turning the ignition on for the fuel pump to prime??? well THAT was the problem. the pump was shooting fuel through a clogged filter because I had switched the lines around. The filter was soo clogged that the pump forced fuel through and cracked the cheap ass plastic filter. Fuel being forced through this small fracture was the PSHHHHHHHHHH sound, not pressuring the system, and simply pumping fuel from the tank back into the tank via the filter leak without getting to the throttle bodies.
I replaced with the suggested Napa part 3032.
I've ridden for a few days now and the bike is running better than it ever has.
For those that hear the PSHHHHHHH sound. Check your fuel filter
All this just to wrap my exhaust.
