BSA Rivet, filler cap, 2 and 4 gallon
A rivet for attaching the filler cap on 2 and 4 gallon steel petrol tanks.
Part number 68-8191 is a rivet used with the filler cap on the steel petrol tank, listed for the 2 and 4 gallon tank sizes. It's a small fastener rather than a whole assembly, so if you're rebuilding a tank or fitting a replacement filler cap, this is the kind of hardware you'd want on hand rather than trying to reuse a tired original.

The catalog ties this rivet to the petrol tank figure, and it also turns up listed under the twin seat figure, which is common for small hardware that gets grouped with whatever else was on the same parts-book page. Don't read too much into the twin seat listing - the description itself is clear that this is a filler cap rivet for the tank, not a seat fastener.
Our catalog record only ties this to the 1969-1970 span across its appearances, so if you're working outside that window, give us a call and we'll check fitment before you order.
