Hey Marc,

1. Did you replace the injectors or just clean them?
A= No, only cleaned and tested, tested for pulsation and flow precision

2. If you cleaned them, how did you do that?  They look very shiny.  :^)
A= Wire brush...and Solvant (Varsol/degreaser/brake cleaner)

3. There seems to be something on the new smaller O-rings.  Is that
petroleum jelly or what?
A=There is no need to put anything...but i do, i use some automotive gasket
sealant.

4. I'm assuming that doing the passenger side injectors is harder as
they seem to be harder to get to.  Are there any tricks to making that
job easier, like removing something else to get to them?
A= Just remove the air-box...after this one is out, it as easy as the left
side, the air box is very easy to remove, 1 clamp, 1 clip, harness and it's out.

Cheers, Ben
