Ron, both my '48 GMC and my '48 Chevy have 'gasoline' on the gauge. Jim Carter's catalogue shows a part number difference for the '52-'53 Gauge Refacing Kit, which uses a 90 mph speedometer as opposed to 80 mph speedo for the '47-'51. Maybe they changed the word 'gasoline' to 'fuel' for the later models but I think you have the right decals for your truck.
