Anyone have one laying around??

I need the measurements for a feel pump for the GM 6.0 motor. I am building a fuel tank with my dad. The fuel pump is not here yet. But I would like to know what size hole to cut in the cut in the top of the tank. I was thinking it is a 4 inch hole but wanted to make sure before I went to cutting things.

3.925" fits the gasket pretty tight.

Thanks that's perfect. Is that with the o-ring or the gasket that slides down in with it?

The outside of the gasket that it sits in.
