A little help needed, some confusion on fuel line routing

[crashoverrideplik]

I just picked up a 49 state bandit 400 off Ebay. I'm having troubles with re-connecting the fuel lines properly. I have 4 lines instead of 3. I assume that the line from the bottom of the carb rail is the feed line from the front of petcock. The one on the rear goes to the vacuum port on the number one cylinder. Lastly the vent nipple on the tank hooks up to the hose that goes back to the coolant tank area. Where does the line from the top center of the fuel rail go?  or do I have this thing all screwed up and sideways.....

Found it in one of the downloads    but the SOB still won't start

Probably not entirely useful to you anymore, but in case someone else has the same question:  the hose from the top rail of the carbs is a vent hose.  It's routed straight up and then lays down the back of the air box.

And whenever my carbs are drained it's easiest for me to refill them (at least partially) manually before connecting the fuel line to the tank.  This way I don't have to suck on the vacuum hose or wait / wonder about them getting filled.

I don't know what kind of bike you've got, but on the bandit 400 fuel tap, there's a screw in the face of it that limits the rotation. If you remove it and turn the tap past it (pointing up) it'll let the fuel flow without the vacuum.

Thanks for that.  That's one of many things I've picked up here. :)

Usually when I pull the carbs -- like four times this week! -- I'll drain the bowls into a small aux tank.  Instead of just pouring it back into the tank I'll leave it in the small tank and pour it back into the carbs when I'm done.  That way I know they're full (except for any random spillage) and I won't try to overfill them.  It also prevents running into any over-fill problems like when I find out after starting up I find that *somehow* I tore or left out a gasket or whacked the floats.  (Der...)

Been there and done that but I'm proud to say this year I haven't pulled the carbs once... and I even put her to sleep last winter without using stabil...
