Had one on this engine. The multi layer Mr.Gasket insulater. And "yes" to the electric fuel pump switched for hot starts. Used that method on 2 of my cars and just installed it on my driver now for the embarrising "Hot" starts.

Is this the Mr. Gasket setup you're talking about?

Does it do the job? I was skeptical that anything with aluminum in it would insulate as well as a 100% non-metallic spacer.
