Hi, I'm looking at replacing the injectors in a 2007 Yukon 5.3L Flex Fuel. The GM parts sites list two part numbers:
12594512 aka 2172436
19421333
Rockauto specifies the 2172436, but I'm having trouble finding clear information on the fitment differences between the two parts. Can anyone clarify for me? Thanks!
