I have a question about My 95 GS-T's fuel pump

i have a 95 eclipse GS-T that is quite modified, this morning on my way to church i had it up to 15 psi and the fuel pump starts kicking now i have a 3000gt VR-4 fuel pump how much PSI can a VR-4 fuel pump handle?

3kgt pump is a densor 190, give or take. PEople have trapped over 120 mph on that pump. Cant go by PSI, because your car at 20 psi and my car at 20 psi have compeltely different fuel requirements ;) It will be good for more than a 20g can put out, roughly.
