2FAST7S

I have searched for the past few days and I'm coming up short...I'm hoping the last 4 numbers refer to a sort of batch or production date.
I'm just trying to confirm I got another supra pump before i put it in.

According to my search the last four numbers are 1020 for the tt supra pump mine are 1270...anyone know what these numbers mean or if it is the same pump? I'd rather get an opinion as opposed to sending out to get tested for $50.00(it may be the better choice-but its going in as a dual pump setup).
