WASHER,OIL TANK FEED
Fiber sealing washer for the oil tank feed fitting on Triumph oil tanks.
This is the washer that seats under the oil feed fitting on the oil tank, sealing the joint where the feed pipe connects. It's a small part but it's the kind of thing that turns into a wet frame if it's missing, hardened, or crushed flat.

The catalog lists it as a fiber washer for the oil tank feed connection, and it shows up across a long run of oil tank figures from the mid-60s into the early 70s. If your parts book shows F1713, that's the older reference for this same washer.
Worth keeping a couple on hand since these compress and harden over time, especially if the tank's been sitting or the fitting's been in and out a few times. Check your parts book against the fitting size before ordering to make sure it matches what your oil tank takes.
