Norton Hose
A Norton Commando fuel-side connector hose used at the carburetor mountings and air box, catalog number 06-4180.
This is a fuel-side connector hose, part number 06-4180, showing up in the catalog under the carburetor mountings, air box, and fuel line figure. It's a Norton part, not a Triumph piece that wandered into the wrong bin, so if you're working on a Commando this is one to check against your parts book.

The catalog only shows this one appearing in a single listing, and the year range on file is 1975, so this looks like a later Commando-era piece tied to the air box and carburetor mounting arrangement rather than an early bike. Beyond that we don't have more detail on it in our records.
If you're trying to match this up against what's on your bike now, bring the old hose or your parts book page in and we can confirm before you order.
Sorry if we got something wrong here. If you think this information isn't correct, .
