So I'm pulling the passengers side valve cover to replace the gasket, but the fuel lines run over the back side of it. I haven't run the truck in a couple days but when I pulled the lines off fuel started coming out. My question is will a minimal amount of fuel come out or is it gunna pour fuel out for a bit?

Should be minimal. Just place a rag where you disconnect the fitting.
