need expirienced ae86 owners..webber carbs help..frustrated

[joon900]

my 4age has 40mm webber carbs...i was running a facet fuel pump which was deemed terrible for the carbs because of the lack of volume it put out...the facet put out about 7-8 psi and had a pulsating fuel delivery....that is the reason i thought my car would die after about 5 minits with out using the gas pedal...so i got a carter p4070 fuel pump which delivers 5 psi at 70 gal. per hour...i had heard a good volume was what the carbs needed...so i install the fuel pump..crank the engine...and it runs for 3 minits before gas starts leaking out the front of the carbs...gas also leaked out the back of the carbs..im hoping i didnt blow the seals on the carbs...my thought is the carbs wer tuned with the facet pump so they werent set to run with the carter pump..anyway i need some help with this issue...i got my information on the internet...what do u guys think?
