A 3.6 US gallon gas tank, Triumph part 83-5414, listed in the gas tank and twinseat section of the parts books.
This is the fuel tank listed in the parts books as a 3.6 US gallon gas tank, part number 83-5414. It shows up in the GAS TANK AND TWINSEAT section of the catalog, which is where you'd expect to find it — the tank sits up top on the frame's backbone, ahead of the seat, and holds the fuel supply that feeds down to the carburetor.

The catalog record for this one spans 1974 to 1977 across its listings, so it's tied to that stretch of production, though we don't have finer detail on exact model application in our records. If you're trying to match this to a specific bike, give us a call and we'll go through it with you before you order.
A gas tank like this is a straightforward but important part — it needs to seal properly, mount solidly to the frame, and clear the top of the engine and the twinseat behind it. Check your existing tank's mounting points and fuel tap fitting against this one before swapping it in.
