There's no way to create the same effect on the quads with squats that you get with the biceps and curls (as an example). You can get closer by not going deep, but there are still too many major muscle groups to pick up slack as your quads fatigue to achieve the same levels of fatigue you can get in a single joint isolation exercise. You can get something in the same family of thing, but different imo.

I too have felt the intense burn/quad fatigue from doing squats and experienced the existential crisis one can get from deads or squats-- but my first instinct (and skepticism) is going to be to question either the range of motion on the squat or how extreme the pump effect you are reporting truly is. I suspect the leg press machine will actually give you that (but I don't use it, so don't know).
