Any Body Knows What The Original Part # For The Oil Pump For A 98 Ta?

 

The Reason I Was Asking Is I Bought A New Oil Pump(# 12586665) And The # On The Pump Is 12556436. When I Look At The Old Oil Pump # It Was 12556436 Which Is The Same As The New One. I Have A 98 Ta. I Tought That The 98 Had A Different Part#. I Did Buy The Car Use. Maybe Some One Else Had Change The Pump Before? I Just Found It Rare Why Some One Change The Pump And Not Change Some Thing Else? The Car Was Stock When I Bought It/

 

How Do U Make The Stock Pump Have More Pressure? OR SHOULD I JUST LEAVE IT LIKE THAT?

 

Interesting, those are the same numbers on the LS6 oil pump I ordered from Scoggin Dickey. Maybe they will chime in and clarify.
