Just some thoughts of anyone owning a 33 Chevrolet Master car gas tank especially when filling up your gas tank with issues for the gas to back up and spilling over onto the rear gas panel! Here’s a few pictures of what I believe is a 33 Chevrolet master car gas tank plus a SST replacement tank! I like the way the filling gas neck goes directly into the top of the tank versus my 34 Chevrolet Standard SST gas tank which all the times when filling either the filler gas nozzle shuts off or if I go a lot slower than my tank gets over filled with splash over! Thanks in advance!
