13/163 Banjo bolt washer
Banjo bolt washer for Amal Concentric carburetors, used at the fuel line banjo fitting.
This is the banjo bolt washer used on Amal Concentric carburetors, the kind of small sealing washer that sits under the banjo bolt where the fuel line fitting connects to the carb body. It shows up across the Amal Concentric Mk I and Mk II carburetor figures in our books, including the T140V, T140E, T140E-T140D, and TR7RV listings, so it's a part that gets specified again and again wherever a banjo fitting is used on these carbs.

It's cheap to overlook but it's the thing standing between a clean fuel connection and a leak or a weep at the banjo joint. If you're rebuilding or servicing an Amal Concentric and pulling the fuel banjo apart, this is worth replacing rather than reusing if the old one looks flattened or nicked.
Our catalog also carries this under the same number 13/163, which is listed as the newer factory number superseding this part number, so if you see 13/163 on a parts list elsewhere, that's this same washer.
