If I buy a used radix for an 04 and up GMC Sierra, are there any other parts that I need to make the conversion besides a inline fuel pump to work on an 03 GMC Sierra? If so where can I get them?

You will also need the return style fuel block that attaches to the rail and accepts the FPR. Just give Magnuson a shout and tell them what you want to do. They will let you know exactly what you will need and the cost. Or contact one of the Radix vendors on here.

 

thanks for the help
