305 TPI to 350 TPI do i need a new fuel pump

Hi, I just got a 350 tpi off of a GTA. I have an 1989 T/A with a 305TPI. My question is do I need to get a new fuel pump that can handle more fuel or not?

Thanks

umm not to be critical, but why swap your system
for something you already have?? the throttle
bodies are the same, the tubes are the same,
the plenums are the same. maybe a larger injector.
but i dont see why you would need such a system,
you already have?
unless its an aftermarket intake and tubes...
all that labor and no difference...

Because he has a complete system and needs the larger injectors for future mods. That way he doesnt have to tear the intake apart. HE will still have the parts off the 305 after he pulls it. you cant just leave the intake setting in the car and pull the motor out from below it.
