Looks nice. You might consider going all-in with locking fuel caps.
Also, the basis for the sticker you got in the kit is from 49 CFR 393.67:
(12) Overfill restriction. A liquid fuel tank manufactured on or after January 1, 1973, must be designed and constructed so that—
(i) The tank cannot be filled, in a normal filling operation, with a quantity of fuel that exceeds 95 percent of the tank's liquid capacity; and
(ii) When the tank is filled, normal expansion of the fuel will not cause fuel spillage.
