Fuel & Vacuum Lines

[jonm61]

Hi all! Well, after much trouble and a lot of work, the beast lives! I have a small oil leak that's dripping on the exhaust plus a few other little things to work out. This is on my '86 ZX900A3.

I need help with the fuel & vacuum lines. I failed to label them when I took them off (oops!) and it's been so long (I hadn't expected it to take this long!) that I can't remember where everything goes. Obviously, I've got some of it right, because it did start & run. I looked in my FSM, Clymer & Haynes manuals, and there just isn't anything that details what goes where.

What I have so far, that I believe to be correct, is the fuel line running from the petcock to the fuel inlet that's between the #2 & 3 carbs. I have a vacuum line that runs from the petcock to carb #2.

What I'm not sure about are the following:

1) What line connects to the fuel level sending unit? It's got the electrical connector & the a hose connector.

2) What runs from the 2 pipes exiting the rear of the tank, and where to they go? Is it one of these to the fuel pipe between the #1 & 2 carbs & the other to the fuel pipe between the #3 & 4 carbs? From what I got out of the FSM, I thought those were only used in the CA Emissions models, but there's fuel coming from them.

If anyone can help, I'd greatly appreciate it!

Thanks!

On mine (1982 KZ1100), this contects to a drain line that runs down behind the transmission. I believe the only purpose is to keep fuel from dripping down on your engine in the event that the sending unit develops a leak.
