I just replaced the fuel pump on my '82 GL1100 Interstate. The new pump came with the plastic spacers that go between the pump and the neck and that go between the neck and the cylinder head. In doing so, I tore the thin gasket going from the 'neck' and cylinder head. The plastic spacer is fine. I've assembled without the gasket but with just the plastic spacer. The assembly between the pump and the neck have both spacer and gasket. Do I risk any damage by not having that particular gasket? The old pump has that spacer intact with the gasket that I could swap if need be. Am I safe??
