The fuel tank in a 54 suburban differed from the earlier Suburban by having the fuel gauge sender and fuel pickup in one unit and that
unit entered through the top of the tank.
It is my understanding (but, I am not certain) that the suburban tank that Jim Carter sells has openings on the side AND on the top, to allow it to be used on 1954 Suburban.
Yes, all 1954 frames are different from earlier frames. The rear-engine cross member is different and there is a
difference in the "kick-up" in the rear.
