On my bench right now are 2 banks of 70's carbs; one parts rack, and one for a customer. The customer's carbs have the same small fuel T's (like the ones for the vents) as fuel inlet T's. My parts set has the smaller vent T's in the vent holes and the larger/longer T's in the fuel inlets. There's not much to see on the Yamaha diagram except a couple T's showing the same part (71). So, oddity or PO BS?

Tee Size Revisited?
See this thread:
http://www.xs11.com/forum/showthread...&highlight=tee
I'll say that when I was dry fitting the shorter Tees into the fuel inlet they were a bit sloppy IMO. (They seemed to fit correctly into the vent orifice though...) That was odd to me cause s'posedly the orifices are the same dimensions.
In my case I wasn't comfortable using the shorter tees for the fuel inlet and re-made my own long tees.
I got a definitive answer to the question of does size/length matter and did what was required to install the longer Tees for the fuel inlet. I'd say that PO shenanigans are why the shorter Tees are being used for fuel in your case. (They may have been the only ones available or the PO chose to go for the least expensive part #/Tees...)

I'll agree with the PO thing; both sets of early carbs I have had the long/fuel and short/vent tees installed, and I know the set for my '78 were unmolested. And like Larry, I found the short ones were sloppy in the fuel holes...Fast, Cheap, Reliable... Pick any two

I have one set of early model carbs and the Fuel T is definitely the longer one on this set. I am a recent owner and there surely have been multiple POs, so I have no idea the complete history.Life is what happens while your planning everything else!

Tee Time???
81xsproject,
Warms my heart to know that your carb "rehabilitation" service includes breaking the bank apart and looking in places the sun ain't shined in decades: Fuel tees and those orifices.
Makes me wonder if latexeses ever got his version of the fuel Tees into production mode:
