I was wondering if anyone looked at the expanding model of the universe in terms of a vacuum pulling the universe out rather than an explosion pushing the universe outwards? Or explain why this model would not work?

In the classical Newtonian mechanics the vacuum is simply a medium that does not oppose any resistance. In order to travel through vacuum a material object (a celestial body, for example) needs an initial speed or a force acting on it.

The apparent suction of vacuum is simply an illusion.

you cannot look at the expansion of the universe -- or say the big bang -- as being comparable to an explosion. Every point in space drifts away from every other point in space. This is different to an explosion, where you have a real center. The latter aspect is missing -- or say different -- when you look at the expansion of the universe. Here you don't have a center. I think, this is an aspect you should keep in mind, when asking this question. Hence, the vacuum pulling inside would also require a center towards it is pulling, in my opinion.

Best,
