where to get copper crush washers (fuel pump)?

[area53 at validpath.com (Jeff Toomasson)]

Hi all - found out that the problem with my new S was indeed the fuel pump. I 
swapped in an extra I had and got it running, but ended up having some leakage. 
Granted it was around midnight and I may not have as been as attentive as I 
should have, but I wanted to replace the copper crush washers to eliminate that 
from the equation. FLAPS and dealer don't stock them. They're apparently the 
same size as for the fuel filter - anyone know if Orchard or Home De-pot might 
carry them? Or do I have to go buy another fuel filter to pilfer these?

Thanks!  Jeff
