Hey All! So far the fuel evap separators have been a success, so I'm thinking about adding another product to the lineup. I've been doing a lot of research on charcoal canisters, and I'm working on a prototype.
In my mind, this product is more like 3 that work together:
I'm also curious if folks are interested in something like this, or if this seems like a fools errand. I thought it would be a good idea to check in before I got too crazy... Unlike the evap separators, this would be entering a market that already has a solution (the Redline kit is still available and I am one of their customers for this kit). Overall, I want something that is serviceable and a nicer/more-stable bracket setup. As I have learned more about the evap system (and because I generally cant help myself), I want to tinker with a better purge setup as well.
Anyways, thought I'd toss that out there!
In my mind, this product is more like 3 that work together:
- A universal-fit charcoal canister designed to be serviced (such that you can open it, clean it out, replace the activated charcoal pellets if ever needed, etc.). A lifetime, non-disposable part. Similar to the evap separators, I'm planning to reinforce the port bosses and use Brass or SS NPT fittings
- Replacement brackets that bolt to the stock mounting locations (and potentially to other locations that are more preferable). I think I can build brackets that would work for both the OEM and new universal-fit canisters if I think it through (more on that later).
- Purge valve options:
- A "simple" option, likely similar to the Redline kit (a vacuum-actuated valve), but with a restrictor on the purge outlet to reduce how much the canister purges at high-vacuum (this option purges at idle when the vacuum is highest, and when the engine is cold, neither of which is great, but its simple and it works). This option would be great for folks like me who have a de-smogged rig, and don't know (or care) if their emissions computer is working
- An "optimal" option: A 12v solenoid valve on the purge outlet with some additional components to activate it when vacuum is in a sweet spot (gentle cruise) and the engine has had time to warm up. This would need a 12v lead from the ignition circuit (tied into the fuel cutoff solenoid or the feed to the coil). This option would be for folks who are super opinionated about air fuel mixture but also don't have an emissions computer (or their truck predates that stuff)
- A stock "plugin" option that uses the same connector as the late-model 40s that have canisters with the purge solenoid wired into the emissions computer
