Vapor Canister - Fuel Smell in cab

[Bronco_007]

Anyone have a good lead on where to buy a replacement for my factory charcoal vapor canister? Gotta get the fuel smell inside the cab under control. Thank you!

You’re talking about the one that sits behind the panel next to the driver shoulder?
I thought somebody was talking about reproducing those, but I’m not sure. However many of us have successfully resealed them since sometimes they split along the seam on top and that can simply be gooped up with fuel resistant sealer, re-glued, or just resealed by melting the plastic.

Or you could do what all the manufacturers did by the 77 model year and get the any fuel related items out of the cab.
For Broncos this was done by utilizing a different charcoal canister mounted up high on the firewall under the hood.
It’s probably the cleanest solution, but takes a little more work.

I’m talking about the one mounted to the frame behind the passenger wheel.

I think I got mine from rock auto cheaper, but see the link: https://shop.advanceautoparts.com/p/carquest-premium-vapor-canister-cpn1092/12448826-P
These can be mounted to the firewall like Paul mentioned

Does this happen all the time, or primarily after you fill up the gas tank?
Do you see if you were leaking out of the charcoal canister on the frame? How are the two larger hoses routed?

Look just inside the drivers door to the back quarter and see if there is a screwed on metal panel just behind where the driver’s shoulder would be. Or behind the roll bar if that’s something you have.
Or worse, behind the pleated rear quarter panel cover if you have a Ranger.

From 1972 to early 1976 Ford use the design like you have, with the canister mounted outside low on the frame and a plastic condensing tank mounted inside the cabin.
In 76, for a 77 model year mandate, everyone was required to get fuel out of the cabs and cabins and keep it outside where it belonged.
In the case of the condensing tank inside, that’s usually where the worst fuel smell comes from. But of course they can also come from a leaky fuel tank under the floor.
What makes you think it’s from the charcoal canister?

I am guessing on the charcoal canister, so i could be completely wrong. I just figured the charcoal canister would need to be replaced after so many years. Not the case?

It happens all the time, full tank or empty. Really bad when I drive it. I don’t have a Ranger so I will check the panel behind driver shoulder per your advice!

This is a picture of the fuel vapor canister that is located behind the drivers side rear quarter panel and is plumbed to the charcoal canister.

You guys are the best. I’ll find it.

Same as mentioned earlier. Seal the crack.
If one of the hose is leaking, patch it if possible.
If it’s the tank that’s leaking, patch it if possible.
If it’s not possible then just replace it with the newer design and get it out of the cab.

My bad, Paul. I went and reread your advice after the last reply. Thank you and sorry for making you repeat yourself.

 

[DirtDonk]

Nope. Not a problem. Sometimes in repeating myself I find an mistake I made earlier!

It's not just a fuel vapor canister, it doubles as an expansion tank. It's a fuel/vapor separator. Here's a picture of mine in front of a LED headlight, which only has 3 lines going to it as my Bronco didn't come with an aux tank.

The two outer lines have plastic tubes extending to the top of the tank, the center line has no tube. The center and right lines go to my fuel tank, and the left line goes to the charcoal canister mounted on the firewall.

Here’s a write up of what I did, had a terrible fuel smell due to tanks not being vented, now my Bronco can sit in garage on a 100 degree day and no smell at all… even with garage door open and sun hitting the tank…

We have used the Vapor Trapper that we bought online. it is a very high quality part that is very easy to install. It is a charcoal vapor canister that you can install oin any application. I think a few other here have used it as well.
