Just did the blazer pump swap 2 nights ago.

I didn't cut the cup, and I didn't tee off for the little feeder line for the venturi system, I left it unhooked while I was doing it.

Once i finished the car ran fine, but I started to feel the pump cutting out more and more often, so i figured that because i didn't have the little feeder line connected, the pump was sucking the cup dry. So i figured the only way to test this theory was to fill my tank all the way up. Even after my needle was pinned on F, same issue. Bad pump? I still have a stock FPR with a AFPR on the way (aeromotive). `could this remedy the problem?

Feels like the pumps cuts out right when i go to get on the gas to take off, and sometimes right in the middle of boost

I have a 2002 OHV Cav, 5 speed, Garret T04E .42 A/R compressor, Ford red top injectors, and running 7lbs. Im sure i left some necessary info, so yell at me if something crucial is missing
