I just finished up a s475/lq4 build for my buddy's 1500 gmc. He wants to put 80 lb siemens dekka or equivalent injectors, but wants to use the stock plastic fuel rails (return style) without spacers and pigtails. Does anyone know what part # is needed to achieve this? Thanks in advance.

 

bump. I'd like to know too. Anyone know if you can just use deka's with spacers on the rails with new pigtails?

Update:

Heres the answer.... to my question about deka's with spacers

I guess a 3/4" spacer will work on the rails so these taller injectors will work. I'll give it a try and post back.
