Note: This is a 2-Port fuel pump (1 Inlet, 1 Outlet). It is designed for 1966-1967 Cadillac 429 engines. These vehicles typically utilize an external fuel filter (AC Type GF124) mounted near the carburetor which handles the vapor return line, rather than the pump itself. This pump replaces the 1965 specific pump (AC 40181) and does not fit the 1968+ 472 engines.
