Looking good. I've got that body style Suburban, but I have a straight axle swap. With all the room that I have I could put just about anything in there.
Don't waste you time with marine injectors.
Mylex International has really good prices on injectors.
Accurate Diesel has great stuff, just more expensive.
NAPA online has the grommet for $3.49 part number is NOE 7031301. They also have a CDR valve but it's around $100. O'Reilly Auto Parts also have the CDR but they call it a PCV. Don't know their price but the part number is EC245.
Ferm,
I've been wondering why others weren't doing what you did. This mod is on my list of to do mods but I haven't had any trouble out of my old alternator yet. I haven't actually seen this mod in person yet. Is you bracket completely straight?
It's actually a very neat setup. The reason that I want to keep the factory breather is that I have a great 4" cold air setup coming straight from the grill.
