Yellow flakey stuff?

Yellow flakey stuff?
I'm doing the fuel filter o ring rebuild on my 7.3 van. I'm cleaning everything up before I put it back together, and I notice there is this thin, flakey, yellow stuff on the body of the fuel filter housing and on the lid that goes on the fuel filter.
Not hard to get off, but...what the hell is it?
