More reliable than electric fuel pumps, this pump is highly preferred over the electric pumps for our performance and competition cars. Manufactured by CARTER, one of Fords OE suppliers, this street pump is rated at 120 gallons per hour with 7-8 psi of fuel pressure. The competition pumps deliver 172 gallons per hour at a constant 8 psi of fuel pressure. No regulator is required with single or dual four barrels.
