The big changeover to fuel pumps came in 1960. So, all the fleetwins/AD models had pressurized fuel tank systems because 1958 was the last for the Fleetwin/AD models. It is not too tough to convert these engines to fuel pumps, you just have to find an intake bypass cover with a fuel pump port/mount, then plug the pressure port on the intake manifold.
The author of this thread talks of having only single line fuel tanks and wanting to use them on Fleetwins/AD models. I understand this concern but feel there is one problem with this plan. Fleetwins/AD models absolutely MUST be mixed at 16:1 due to the plain bushing rods, regardless of modern oil claims. I am "asssssuming" his current single line tanks are mixed at a lighter oil to fuel ratio, so using single line tanks from other OMCs would make it very easy to inadvertently use the lighter mix on his future Fleetwin/AD model.
