Mark, I have a 3400 IPL from 1980 that doesn't show that gasket.Does anyone know where I can find one or two of the foam tank seals for the 3400/3700/3800 model? I find both PN 19093 and 19122 depending on which IPL I look at.

They are out there but at a high price. If you want to make one up just use some closed cell neoprene weather stripping and if you can't get a piece wide enough glue the pieces together with crazy glue. The original is just black foam.
