If you're going to register this rig in The Peoples Republik Of Kalifornistan, be very concerned about smog testing. Unless you live in a county that doesn't require smog testing, a trip to a smog ***** will be needed every other year.

I'm not sure a CNG rig is exempted but I would check before I just brushed it off.

 

Thanks. But in my situation I don't have to worry about smog testing.
(if perplexed PM me).

 

Update:
I sold off the van for a small profit. Large if you factored in all the gear I sold separately over 2.5 years from the van.
I probably mentioned it but I also posted up largely very similar information to attempt a conversion to gasoline here:
Planning to remove all CNG components from my '98 Ford e250 van. Qs. - Natural Gas Vehicle Owner Community

There are at least 2-3 parties who have gone through with the conversion. The last one contacted me and thought he had a wiring issue and did some unnecessary replacements and deleted the AFCM which I would not normally advise. Or it could be fine, but you would have to make sure your fuel injectors are wired up receiving power to them as the AFCM is the last in line and intercepts the main PCM pin outs power that normally go straight to the injectors (with a CNG Ford those power wires are instead routed to the AFCM and adapted for a different OHM resistance power for the CNG fuel injectors. The power may be ok for gasoline as is from the AFCM, but it may not be. I never followed up with an electrician to see if the different resistance was ok).

More interesting discussion here that I had posted stuff on:

Wouldn't it just be easier to pay for the hydro test on the tanks and get a recert? That's all we do for our CNG fleet vehicles, gives us 5 more years at a time. I have had only one ever fail the recert.

 

Not if the tanks are expired. there is no recert.
also CNG sucks. Who wants to deal with it? It's a complete p.i.t.a.

 

Who wants to deal with it? I certainly would for today's posted price of $1.54 gge at the local CNG fill that I pass everyday anyway.
