AS I browse this site, it seems like natural gas as a fuel is reserved for vehicles originally built for it.

In my youth, I noted but never investicated propane conversions for carburated cars which were purely add-ons which allowed propane or gasoline use.

Assuming an older, non-emissions controled, carburated vehicle like my 66 4WD Suburban, is there any system that allows the use of natural gas?

Thanks, George

Welcome. As to your 66 Burb, the only emmisions device is a pcv valve. The vehicle is exempt from smog check in ca. The conversion would use the same fumigation equipment as lpg (mixer) , but substitute a high pressure regulator for the liquid to gas vaporizer.Plenty of Impco or Century equipment to be found on e-bay.

The tank and lines are another matter. Compliance with nfpa52 ( specific regulations on tank and lines, mounting , routing , protection , fuel lockoff ,etc).

CNGHAL , CNGMIKE , AFVMAN or others are experts and can help.
