Technically speaking, it should run until it burns up.
Proceed with caution.

I wouldn't do it.
You are going to need a way to drastically raise the fuel pressure when under boost anyway. The system only runs at 9-12 PSI any way, now put 8 psi on the outgoing side, you now only have 1-4 psi of fuel pressure, yuck. The factory TBI pump will put out about 15 PSI max. I would go with a Walbro 190, use a FMU with about 4:1 rising rate, retard the timing 2-4*, and go from there.
Keep in mind that Rbob's, EBL is 2 bar MAP sensor compatible for supercharged engines.
