I have a 93 Bronco with a 351W/5.8L, E4OD transmission. The truck had been sitting since 2006 until I had a used engine swapped in a few months ago. At that time, I was told that the smog pump was seized up. Since the truck is too old for IL emissions testing, I replaced the pump with an idler pulley. The shop that installed the engine left most of the other emissions stuff in place, so I'm trying to figure out what else I can remove. Can I remove the coffee can looking canister on the passenger wheel well in the enclosed picture? What about the component in front of the canister that is in the second photo? Can I remove the catalytic converter? The O2 sensor is upstream from the catalytic converter, so I do not think it will be affected. Is there more stuff that I can / should remove.
Thanks,
Steve

Yo fyreduck1921,
The emission vacuum tank feeds the HVAC vacuum tank for Heater/AC operations as shown below; it can be replaced with a 96 tank that is made of long plastic plastic, check e bay.

Your 2nd pic is the smog pumps filter;

It can go along with the muffler or save to sell.

Following emission related deletion parts are commonly used & available via google searches:
You are looking for Thermactor (smog pump) Plugs, some use 5/8" by 11 by 1" SS bolts while others have welded holes closed.
Stainless Steel Thermactor Smog Plugs the holes in the back of your cylinder heads when removing the exhaust crossover tube. Comes with 2 stainless plugs and Loctite. Hex head makes installation easy when the engine is still in the vehicle.

"...What you need to do is electrically plug in the TAB and TAD solenoids but remove the vacuum lines, then all the air injection plumbing and valves can be removed and the heads plugged. The EGR is a seperate system from the Thermactor and the computer treats it very differently, it also helps increase milage and power so it's a good idea to keep it anyway. If you have the DPFE system there is no way to bypass it without the computer knowing and throwing a code so you may as well keep it intact. you'll get codes if you remove the solenoids, the easiest way to avoid this is to just leave them plugged in. The TAB and TAD you could fake out pretty easy, but even the old EGR system can't be faked because the computer both commands valve movement and watches for feedback to confirm it happened, so a dummy resistor won't cut it.

A neat mod by jrichker; "...Put the resistor inside the heat shrink tubing and crimp the connectors on. I would choose the Ford pin connectors since they should plug in the TAB & TAD wiring. That way you haven't modified the wiring so it is easy to re-install the TAB & TAD solenoids if emissions testing comes to your area. 18 gauge crimp on taps..."
read more and see many pics.

miesk5 Note, see EVP pins by SeattleFSB @ http://www.fullsizebronco.com/forum...-position-evp-sensor-testing-replacement.html

"here's an even easier way; once the EGR valve is removed off the car, remove 3 small (7mm?) screws to disassemble the pintle assembly (EVP) from the EGR valve body. plug the EVP back into the wiring harness and push the steel pintle in about halfway and using strong tape (green or red duct tape works best), wrap the tape over the pintle so that it holds its halfway-in position. hide the pintle assembly out of sight. I've run my car like this for at least 5 months now and no check engine light. No soldering needed, no money spent except if you need to buy tape and its still safe and reliable. just remember to put an EGR delete plate over the opening in the upper intake, a cap over the heater tube opening on the passenger side header and plug off your 2 or 3 (now disconnected) vacuum lines." by cobraman1024 @ http://forums.corral.net/forums#/topics/1082197?page=1&_k=wm3nva

Here is Ryan M's now closed parts site @ RJM Injection Tech ? Welcome
Ryan also sold;
Actuator Eliminator Resistor $2.00 each
75 ohm 3 watt Resistors can also be used to eliminate the EVR, CANP, TAB & TAD solenoids.

CATALYTIC CONVERTER;
"am doing that on my 95 5.0, work in a mechanic shop n my boss recamended it so in a few weeks im guna take out my catalitic converters and put straight pipes to my new flowmaster muffler i installed yesterday,then im gunna get hedders, according to my boss the owner and mechanic of my shop says it should sound sick" by ilystbronco

Some just gut the CC.
