Fuel Tap Help.

Hi all,
Regarding my 1980 Z1000 LTD B4. Now I have it running I am going back and looking at a few jobs I "bypassed" to get to where I am. It has a manual fuel tap which I rebuilt with a new seal kit. This has a brass fitting I connected both carbs to using a Y connector as well as another outlet in the same gunmetal colour as the fuel tap body. This just wee's out fuel the same as the brass outlet. I cant think this is right so I am gussing I made a mistake somewhere. I had just capped it off but I was wondering if I could attach one hose to the brass fitting for one pair of carbs and another for the other gunmetal fitting. Sure this wouldnt be correct though!
If anyone could enlighten me as to the correct setup I would be most grateful.
Thanks,

Hi Gaz
Could it be that the slotted internals (pink I think) are 180 degrees out of place?
The part between the tap Knob (No Jimmock not now) and the O ring 15 in the drawing

Thanks Gus, I will have a look. I will try and post a photo as well.
Cheers.

Here is a photo. The brass outlet is round the back and obviously connects to the carbs. The "mystery" outlet is the grey job pointing skyward (it rotates 360 deg) capped off with the pipe and bolt combo.
I will check the tap knob as suggested by Gus.
Would be good to know its official title if anyone knows...
Cheers,

Had a look over the weekend. They both join up inside the body of the tap just inside. You can see by poking a bit of wire in each outlet. I am going to feed one pair of carbs off each I think and see how I get on.
Thanks for the suggestions.

On my z900 the tap has two outlets which feed down to the left two and right two carbs. The reserve part of the tap is achieved by different height pipes on the part which is inside the tank.
Swiss Gaz how many pipes do you have feeding the carbs one or two. In your first post do you mean that the only hose feeding the carbs is then into a "Y" to feed both pairs of carbs.

When I got the bike all the fuel hoses were cut off so I had no idea how they were supposed to go. As the brass outlet seems to look right I ran a single pipe from this to a "Y" connecter that then split the fuel off to both pairs of carbs. The mystery outlet I just left off as it was painted so I guessed it was blank or a breather or maybe redundant but used on a different model. Sounds like I am setting up like you z900 so I shouldn't have any problems.
Yes, the reserve runs off the two pipes in the tank and you switch between the two to go to reserve using the leaver.
Thanks though, as it sounds like this setup should work fine.
