Claim 7:
8. A form-coding system configured for use with a plurality of storage tank filling ports (1) having a plurality of filling pipes (12) extending into an underground fuel storage tank (4) and comprising radial lips (6) defining an opening (2) at its open end, said system, comprising:
a plurality of form-coded collar assemblies (28), each form-coded collar assembly (28) comprising:

a form-coded collar (10) that corresponds to a substance contained within the underground storage tank (4); and
a sidewall (8) extending between a user-facing surfaces of said base plate (14) and said form-coded collar (10),
wherein the collar assembly (28) is formed for attachment around a filling pipe (12), without obstructing the radial lip (6) of said filling pipe (12),

wherein at least two of said form-coded collar assemblies (28) include form-coded collars (10) that differ in shape with respect to each other; and
