just wondering if anyone knows what would be different between a radix kit that fits a 99-02 5.3 over to an 04 5.3? Any help would be great thanks in advance!

 

99-02 has a different fuel system, kit includes an inline pump, a fpr on the drivers side rail and a bracket for the tb cable. 04+ has an intank fuel pump and a different fuel block on the rail.

 

took the words outta my mouth, i had an mp112 on my 02 escalade and we are throwing it on my little brothers 07 classic 5.3. which is basically an 06 model. and we had to order a new fuel block and a new fuel pump

 

thanks sooooo basically I would need a new fuel block to make it work?

 

fuel block needed for an 04 model going on my 03 flex fuel? thanks

 

Probable not, the 04 flex fuel motor I put in my dads 72 was a return fuel system, like the 99-02.

 

mine is a non flex-fuel model
