Just see a dealer , they can fix you up as its all they do is GM parts , after market is crap imo

Two different OEM ones as well. Depends on the tags that are on the lines currently. 1st design have UCT on the tag on the factory lines, 2nd design have KWB on the tag on the factory lines.

How can I tell which ones I have the only tag I can find is a gm part # 15809063 on one of the hoses should I just get the acdelco hoses that have that # or go with dorman hoses, but if I go with dorman which ones are the same as the acdelco ones ?

15809063? Those will be the 2nd design hoses so you would need 15809063 and 15809062. If you do go Dorman, 625-304 and 625-303. However, the list price between the OEM and Dorman lines is around $3, with the Dorman lines being the $3 more expensive pair.
