Hello i need your help
Can you please tell me the code parts for fuel injectors for Marine GM Predator type Vortec 5.7 V8 310hp EFI mod. 2002. The injectors i will never change it (the boat i bought new)
On top of it has this code 17104288 (photo) but told me that is not right for this engine but for the next 7.4L . I"m really confused.
Thanks a lot

You shouldn`t be confused. It is the right p/n for your application.Use this OE throttle body fuel injector for all GM and Chevy 7.4L trucks from 1992 through 1995.
Note: Marine application is 5.7L V-8
P/N: 17113080, 17104288, 17113081
7.4L V-8; 5.7L V-8 Marine
As far as the marine application TBI units I have seen they have only 2 part numbers for the most part. One that is 46# @ 12 psi but flows about 74# @ 30 psi and one that is rated 61# @ 12 psi but flows 104# @ 30. Your injectors are the smaller injectors BUT they were also used in the higher pressure 454 truck fuel systems hence forth the confusion. The 454/502 marine TBI injectors are 25170301.Originally Posted by costas

But why the code is 17104288 is it wrong ? somebody told me it's about for the bigger 7.4L engine, if it's for the 7.4L at 5.7L reasonably going to consume more gasoline ?? These for example are correct ?

You need the 17104288 number injectors. The ones in your link are wrong.
Can you suggest me from which shop i can buy ? whether it is better to get from AcDelco ? has the same code ?
Thanks a lot for your help
