Washer - upper
Upper washer for the gas tank mounting hardware, used on Triumphs from 1974 to 1980.
This is the upper washer that fits under the gas tank mounting hardware, listed in the parts book under the GAS TANK AND TWINSEAT and PETROL TANK figures. It's a small piece, but it does the job of spreading load and cushioning the tank at the mounting point so the tank doesn't crack or wear at the fixing.

Our catalog record shows this number appearing across model years 1974 through 1980, though we can't tell you from that alone which specific model your tank uses it on. If you're ordering, have your tank and mounting hardware in front of you to confirm it's the right washer for your setup.
Note this part was later renumbered to 82-3814 by the factory — if your parts book or an older invoice shows 82-3814, that's the same physical washer under a newer number.
