Im bout to put on some 42lb injectors on my 04 5.3. Is there a special spacer to use? or do I just stack washers? I will avoid the "jerry rigged" look at all cost no matter how minute.

 

If you have the multec IIs you will not need spacers. If you have the ones that fit the f-body you can get some metal tubing from Ace Haedware and cut it down to the correct length.

 

I know I aint got multec II's cause I had to get some different connectors (EV1s). what size of tubing? I would like to have everything prepped as much as possible for install.

 

i believe 1/2"

 

I Do Stacked Washers With Black Tape And They Look Good

 

what works good is if you have the studs for the intake where the throttle body bolts up.

 

I ended up using a 3/4" long aluminum tubing. You have some room to play with for the spacing, the injectors don't need to be pre-loaded down into the manifold. As long as both o-rings are in the bores you are fine.
