I'm going from a 305 TBI to a ZZ4 with EFI.

I know that my fuel pump is in the gas tank. I know that the 305 TBI fuel pump is too small to feed a 350.

Is there a way to add a bigger fuel pump externally (retaining the old pump) so I don't have to drop the tank?

Can you run two pumps in a row like that? If so, any suggestions on what pump to go with?

Thanks,
