CONNECTOR HOSE AIRBOX TWN
Rubber connector hose linking the carburetor to the airbox on oil-in-frame Triumph twins, part number 83-2626.
This is the connector hose that joins the carburetor to the airbox on oil-in-frame Triumph twins, part number 83-2626. It shows up in the AIR CLEANER AND SIDE PANELS section of the parts book, and it's the rubber boot that carries intake air from the airbox back to the carb mouth, sealing that joint so the engine draws filtered air instead of pulling in whatever's loose under the side panel.

Our catalog record runs 1971 through 1974 for this one, and it's also carried the alternate numbers 43-99761 and F12626 in other listings, so if your old parts book shows either of those you're looking at the same piece. It's a simple wear item — rubber perishes over time, cracks at the clamp area, and starts pulling unmetered air, which will show up as a lean stumble or erratic idle.
Worth pulling yours off and giving it a look if the bike's been sitting or if you're chasing a carburetion gremlin that doesn't make sense any other way. Check the fit against your airbox and carb before ordering, since these connectors changed across model variants and years.
