You are correct U.D. Here in the Southeast, the Vickers type Vane pumps were wearing out prematurely. FoMoCo attributed it to "Fine Particulate Dust" in this region of the country. A Factory Campaign was initiated to replace the Vane pumps with the new design Piston Pumps. As you stated a different Manifold was required in this conversion. I myself have never seen a 53/54 model with the original Vane pump still installed here in Eastern NC. FWIW SoS.
