Get a normal Texaco decal from any of the suppliers and have it mounted onto magnetic material. The magnetic material can be found at any 'sign shop' in your area. They should also be happy to do the mounting/trimming for you (for a fee of course)
The magnetic material will conform to the curvature of the pump. As an added bonus, the thickness of the magnetic material also makes the decal look like a porcelain sign.
This is especially true if you purchase one of our decals since ours have a nice shine to them that is not found on normal silk-screened decals.
