If that was important enough, I'd just have a mini radiator/heater core with a fan that stayed hooked up to the engine and hung from it's hoses in to the trunk of the leaf.

Seems a lot easier than trying to plumb one in to the leaf's HVAC system, which isn't designed for it.

Would It be alright to hook up the CNG fumigation carb/nozzle/else before the air cleaner? The problem is that the air filter is part of the plenum. There are 4 individual runners that run from it to the engine. So unless I put on four individual CNG nozzles after the air filter I can't add natural gas fumigation after the air cleaner. So for practical reasons it would be easier to just add natural gas before the diesel's air cleaner.

Here's a VW MK2 diesel air filter: VW VOLKSWAGEN 85-91 GOLF / JETTA DIESEL 1.6 Non-Turbo AIR CLEANER AIR BOX | eBay

Another idea would be to adapt an air intake off of a gasoline, perhaps carbureted VW and wire the throttle open. That way I could replace or modify the carb to something that can fumigate the natural gas into the intake.

Another thing I'm thinking is I could put on a K&N air cleaner on the beginning of the intake and put the CNG fumigation after it. Maybe the second air filter could be left since the natural gas is a gas and should flow through the paper filter element? Or I could cut out the paper element and use a filter's gasket and use the K&N air filter for the only filtering.

The closer you can get to the intake runner the better with fumigation.
You don't need to add a carb to the mix. A carb would just be a restriction to a diesel.

I ran propane fumigation before the air filter years ago, only problem was some times I could smell propane. Once I relocated the injection nozzle to the top of the intake manifold, on the inside of the air filter the smell went away.

I'd prefer a flammable gas/air mix to be as inside the engine as possible, just in case. Right before the manifold, if I couldn't get it in the manifold.

Thanks! I guess I could rig it up inside the air cleaner right below the air filter.

The idea of the carb was a way to meter the gaseous fuel. I'd take the throttle plate completely out. But if there's a better/cheaper way to meter the gas I'd like to hear about it.

Just use multiple nozzles, that's what I did.
