Fuel filler neck measurement

[Michael Allen]

Need a measurement for the filler neck for a 1955 passenger car fuel tank. The center line for the filler neck measurement taken from the right flange as the tank is viewed from the filler neck end of the tank. Looking to use one of the Speedway 55 EFI tanks in my 53. The 55 neck appears to be a little longer and with a bend. However, that I can deal with if the center line measurement is the same as the 53, which is 7". Thanks for the help.
