Am I reading it right that 545K116 is for ~5/16" ID (8mm) hose and the threads are the same as those on a petcock? Also, 545K114 is the same except for ~1/4" ID (6mm) hose?Check here - couple of different barb sizes available. You want 1/4" BSP.

I'm looking to connect an auxiliary fuel supply to my carbs without taking the fuel lines off.
Yes. Disconnect the nuts from the tank, remove the tank, and connect hoses with (BSP?) fittings to the carb lines.How, exactly?
Do you mean a fitting that can be attached to the fuel line tap/petcock 1/4 BSP nut (it isn't BSPT) after the nut has been disconnected?

I had a second look, these might work better - They are BSPP, like the petcocksYes. Disconnect the nuts from the tank, remove the tank, and connect hoses with (BSP?) fittings to the carb lines.
What did you get for the Y adapter?Fortunately, I called McMaster-Carr, cancelled the wrong ones and added the right ones. The are twice as expensive but I will finally have the temp gas tank I've been wanting! Ordered a "Y" adapter too so now I'll be able to connect a standard remote tank to the two fuel lines.
Crap! Simple solutions sometimes escape me! Oh well, I'll have a fancy version soon.I have one of these:

Must have item, when needing to remove fuel tank to perform maintenance on your motorcycle. Eliminates need to balance fuel tank in an awkward position. Simply remove your tank, connect the auxiliary fuel tank, which is gravity fed, and hang it up using the hook provided. Features 1L tank, 950mm...www.sealey.co.uk
I took the silly little valve they supply it with off, and fitted a standard petcock the same as I have on the bike.
So I just screw the 1/4" BSP connector straight on.
The fuel flow is enough to feed both carbs, so if the tank is still on, I can just leave the other petcock attached but turned off.
If the tank is off, I just connect a spare petcock to the other side and leave it closed.
