Question on fuel Ts (1979 XS1100)

[olatheracer]

Hey there:

I took my carbs out, and foolishly took all the Ts out and left them at a friend's place, as I was planning on replacing all four (2 leaked). After reviewing the manual though, it looks like there are 2 different part numbers.

One of the other threads here suggested this, which looks like a match:

I was wondering if anyone else knew if I needed 4 of these, or 2 of these, and 2 of something else.

Im not sure about the one you posted but, you might want to look at the Yamaha parts on that site. Click here...

If the "T"s you are referring to are the the vent and fuel T's that sit between each pair of carbs, it is pretty easy. They are two different widths. If you put the long one in one pair of holes and the short pair in the other pair of holes (between the two carbs), they will only only work properly one way, all though you can but them in either way. I did the same thing when I rebuilt both my carbs this winter and had to play with them a bit to figure out the correct location for them.

Yep, those are the fuel Ts. When you say wider, do you mean the tubes on the T are longer, or the diameter of the tube is wider?

Also, would it be a good idea to add a little inline fuel filter?

You might want to get your old ones back and repair them. They might be hard to find new.

The diameter of the tubes should be the same, one or the other is wider.

Inline fuel filters are always a good idea.

Most of the rubber had worn out on mine. Also, the insides had a bunch of gunk built up.

I ordered them. Turns out that this little guy:

Is the Lower T.
