These numbers are located on that part of
the firewall that is connected to the gas tank. What this study
and database reflects are those dates as compared to the engine
serial number stamping date.
data base shows that there are three possibilities:
date on the tank reflects “before” the engine stamping date
date on the tank reflects the “same” day as the engine stamping
date on the tank reflects “after” the engine stamping date.
thing one never knows is the fact that if the gas tank was replaced
somewhere along the line in the past 75 or so years, then the computed
days would not be correct.
you have a car or truck which you may think is the original gas
tank for that vehicle and would like to put it in the database,
please contact me.
