Charcoal Canister / EVAP Install / Solve Gas Smell

[Broncobowsher]

Need? No.
Can one improve the experience of owning an older vehicle? Yes.
Detrimental to performance or anything else? No.

My two (or maybe three?) transactions with BC Broncos have all been good.

Do I even need a charcoal canister since I’ll never be smog tested in my area?

It’s not so much about passing inspection anymore. It’s about keeping the air clean around your house.
Is it always parked outside? Does that outside happen to be anywhere near the house?
If so, the better course of action is to keep it intact.

I did retain the piece that’s outside of the frame behind passenger wheel, just can’t find the canister.

That bit on the frame behind the passenger wheel is the charcoal canister. The other piece that’s inside the cabin is a recovery tank. Or condensing tank.

It’s been 2 years since we took her apart and who knows where that canister is

You could source another one, or you could do what more people do nowadays and update to the 76/77 version where the newer style plastic charcoal canister is mounted on the firewall under the hood.

Or you could go ahead and eliminate it, and hope for the best.
Some do and don’t really have any issues. More often than not though, you constantly smell gas around your truck.
Just like the good old days before evaporative emissions restrictions.

How do I post pics on here? Found some more parts, specifically the bracket and white thingy that mounts to frame on passenger side, also found a set of vapor lines from Inline Tubing I must have ordered way back when.

You have to be a contributor, which it looks like you already are. Then just click the photo icon at the top of the reply box and click in that “Drop image” box to add a photo or select “Attach files” at the bottom of the reply box and select your photo. Should be pretty straightforward.

Thanks- here’s the piece I was referring to, and yes it will be garage kept right next to my gas furnace so don’t want any fumes …..

That’s the rollover valve. Prevents raw fuel from traveling up the vent line in a rollover.

 

[SeaVee]

Cool- thanks. So IIRC there’s a vapor line from there to the canister on firewall?

 

[DirtDonk]

Yep. Correct.
Nothing fancy, but if you already have a pre-made line, use it.
If you need to use just regular fuel rated hose, you can use that instead.

If you want to see how it works before you install it, blow into the inlet while you rotate it upside down, it should stop the air.

Thanks for that tip, it does work but looks like crap on my powder coated frame, can you still get these? Haven't been able to find one online

Look for a Deloren roll over valve. https://www.deloreango.com/us/roll-over-valve.html

I used the rollover valve from this set (not the vent): https://www.summitracing.com/parts/TNK-VVR-IL

But it has to be mounted vertically. I converted to the newer-style charcoal canister mounted on the firewall, so I put the rollover valve near the passenger fender on the way up to the new canister.

Inline rollover valves seem to me uncommon, here is another: https://www.amazon.com/dp/B0BFHYFFRC/?tag=classicbroncos-20

This might help. Taken from my other DIY canister post.

I was just looking back at some posts and this popped up. This is the kit we are using now. Have installed a bunch of these and no issue have arisen. Quality part. https://www.vaportrapper.com/product-page/vapor-trapper-basic-install-package
