If you're purchasing the Howell TBI, you'll need to get a new air filter and assembly. Check out Sam's Offroad for a kit or to get some ideas. It will be a filter, housing, and spacer. Also if you don't want rubber fuel hose in your system, you'll need to buy steel lines.

People have had issues with the stock fuel return line being too small, causing to run too rich, and had to enlarge it. I didn't have this problem, though.

Besides the above mentioned, the kit is pretty complete. Make sure you order straight through them and have it tailored specifically for you, especially if you have any mods on the engine (cam and headers in my case, others due to coil etc).

Also, you're probably going to want to get zip ties, electrical tape, shrink wrap, solder, voltmeter, patience, and beer.

Good luck!!!

The kit I bought had plenty of fuel line included. I did end up getting a small inline fuel pressure gauge to put just before the throttle body. Not really necessary, but it is nice to have.
You will need to get an air cleaner, or at least an adapter, since the GM throttle body is 5-1/8" diameter. Be sure that whatever air cleaner you choose, it has a provision for hooking up a breather line to your valve cover. A standalone valve cover breather will not pass the smog visual inspection.

Or, try to find a breather from a FSJ with a V8 4-bbl. That way you will have all the connections (PCV, TAC/TVS, EGR etc....) that the smog nazi will be looking for.

The dual CTO valve is forward on the side of your intake manifold, below the water hose coming from the radiator - has between 2-5 little ports coming out of it.

Trying to find a picture of it....

It's sorta maroon in this picture, just below center of the picture:



There's actually two of them in that picture, one maroon and one brass. You only need one, not sure why there's two on that manifold...

Yep - yours has two ports. The thing just forward of it looks like your new water temp unit. See what CARB says, but you may need a 5 port variety. If that's your original intake, they shouldn't have any complaints.

It looks like you have a single CTO valve.

Fromhttp://home.sprynet.com/~dale02/cto.htm
Quote:
The CTO is a thermal vacuum valve and is located in the side of the intake manifold just forward of the carburetor. It blocks vacuum to the EGR Valve and the Evaporation Canister when the engine is cold. It begins to open at a nominal 115 F.

When you go to get smogged, the tech is going to check to make sure that your vacuum layout matches the emissions sticker provided by Howell. The sticker clearly shows a dual CTO with 4 ports.

SLO - good point, it's been a while since I've looked at that emissions sticker

DJ - part number EC957 at Advance Auto Parts is what you're looking for.

So here is what my instructions show. Do you suggest hunting down a 5 port or can I use the two port?
