Well I finally found a multi-pack of copper washers. I found two that were the same size as the originals, only a smidge thicker, maybe 25%, and one that had the same ID but slightly larger OD which I used on the bottom of the stack. Took some time to line it all up, get it snug, center it again, and tighten it down good. Took a 10 or 15 min ride, no leaky. Gonna ride up to Port Jeff with the GF in a few and see how it handles under load, and constant cruising. Like you said, pressure around 20 psi at idle after getting warmed up.
