fuel lines

09 696
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..

[jaxduc]

Yes but they are indistinguishable which leads me to think that it doesnt matter which one goes where.

[jaxduc]

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.

[jaxduc]

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.

Could it be the battery?

Best check with spikec.

And if its not that, whatever the problem, it can usually be fixed with a modified beer can

[jaxduc]

You guys/gals are such a big help

[jaxduc]

serially

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.

[jaxduc]

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.

[ducpainter]

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?
