Injector Washers

[PossumTruck]

Does anyone know a source for/common size for the copper washers that seal the injectors?

I want to pull mine and inspect the tips/clean after a couple years of WMO. I don't think I have any issues, but I want to see what's been going on. Anyhow, I can only find those washers in a format that also comes with the return line kits. I don't need hose or caps, and I have a bunch of viton o-rings - thus, I would love to find a source of just the washers.

I have no idea how bad of an idea it is to reuse the washers, but I would rather not risk it if possible.

Pretty sure harbor freight sell copper washers assortment, for next to nothing. Then you would also gave washers for your oil drain plug.
