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

You shouldn`t be confused. It is the right p/n for your application.

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.

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.
