I did a 4.8 Vortec swap out of a 2000 Chevy truck into my 1986 Chevy truck, and the fuel pump i rigged up from the 2000 isn't putting out enough pressure to run it right. Its putting out about 25 psi right now and i think it needs about 55? Wondering what would be my best best for a new one. Keep in mind the stock pump from the 2000 doesn't fit in the tank for the 1986. How about an inline pump?
