Unecessary Stuff

[packman]

So, I am clearing the engine compartment of things that don't work, are not all that effective, and are just plain broken. Started by removing the charcoal box by the front passenger side fender. I identified the solenoid and a severed tube that pumps into or from it. Also, one of the wires that goes to the solenoid had been severed as well at some point. What was the function of this box? Can I just plug the line that goes to the upper intake?

I think I have some relays or solenoids that go to the EGR on the passenger side fender. If I retain the EGR, I imagine I need still these? I remember replacing the EGR solenoids several years ago when my fuel pump was dying. Hasn't thrown a code yet, so I guess they're still working.

I think I will work my way around the engine compartment and identify what tubes and wires go to wherever, and determine whether I need them or not. So, what do you guys do when you do a HO or a performance EFI build?

When I put my HO in many moons ago I just reconnected everything, checking for broken hoses along the way.

That charcoal canister is the evaporative emissions thing. The gas vapor from the tank & when the car is shut down gets stored there and then ingested by the engine when running. Without that you'll smell gas occasionally if not all the time when parking it somewhere. My Fury is devoid all emissions stuff and so with it's exposed air cleaner set-up I'm always smelling gas. Don't know how those guys did it back then.

Okay, I think I can do without. I am thinking that since the solenoid probably hasn't been working in a long time; the gas fumes would have been present; which I haven't detected. So if I trace that severed tube; it should lead to the gas tank? Hopefully my EVTM has a diagram of how that canister/box is routed. I noticed that the only tube connected to my canister is the one leading to the upper intake. There are 2 other ports that are open. Meh, I am just going to eliminate the box and be done with it.

Next weekend, I will look for more things that should stay or go?

You can cap the fuel vapor line to the tank but the tank needs a way to vent. Make a cut on the seal of the gas cap and roll.

Emissions cars are quite smelly when their emissions are tampered with compared to old stuff that's running well. No smells from my 74 F250 other than light exhaust. Way better than anything efi with gutted cats.

I'd leave the canister in. If the solenoid isn't working, the charcoal still is and will keep it from smelling strong of gas, but without the canister, raw gas fumes will escape unchecked and be MUCH stronger. Ask me how I know.

As would I. You don't think things are bad until you tamper with them. Fury STINKS. Makes me think it's leaking when it isn't.

Just apply 12v dc to the solenoid. If it works just use it.

My car had one line in from gas tank and one line out to solenoid then to upper intake vacuum. Normally this is tee'd with the PCV valve vacuum. Can go to any other vacuum port direct into the intake though.

[packman]

Ugha!!! I was all set on eliminating that canister. Now I am considering keeping it. I will see when the engine comes out. Might just run a small rubber fuel line to the canister and replace the dry-rotted hose that comes from the upper intake.

The canister in the b-body I had (q-jet carb) just vented to atmosphere so you could smell it on occasion... but it wasn't bad. A purge solenoid would have helped that boat.

Yeh anything including the line from the tank attached to the charcoal system can go. I put a check ball type vent in the top of my tank (only seales off if the car is upside-down) to a little vertical baffle cannister incase of sloshing and an 8an braided line off the top of that to a fitting to vent to the wheelwell and have yet to ever catch a whiff of gas with some major hot/cold swings.
It don't take much to get the smell of gas in the air lol

[pantera77]

My 87 wagon had it removed when I got it, I never really smelled much gas.

[sly]

You have been lucky then. Here in Texas, when the elbow from the gas tank into the charcoal canister on my 88 rotted out, you could smell gas around it. And it was an outside car at the time.

[knucklehead0202]

Yeah most "emissions era" vehicles seem to be better with most of the emissions crap hooked up. When I first got my exhaust done, I had no air tubes or cats. This bastard smelled worse than most old cars with poorly-adjusted carburetors.

[packman]

Behind the a/c line, you can see the fuel line with the broken rubber hose still attached. I am going to assume that this is the line going from the canister to the fuel tank? I found the other end of the solenoid wire that was severed; it was dangling in front of the engine. I tied it to another wire that leads to the solenoid. I will trace those wires and run new wire to get that solenoid working again. Might also run new fuel line to the tank if that broken line is what I think it is.
