Ram Trucks 2013 3500 - CNG Supplement - Manual (Page 57)

Container Retest Requirements (Canada)
Each container must be re-qualified by inspection or
testing after a motor vehicle accident and at least every
36 months or 57 000 km whichever comes first, or at the
time of any reinstallation in accordance with Canadian
Standards Association B51–97, Part 2.
Retest dates must be marked on a label securely affixed to
the container and overcoated with epoxy near the origi-
nal test date. Reheat treatment or repair of rejected
containers is not authorized.
The fuel containers expire and must be removed from
service fifteen years from the date of manufacture. A label
on the fuel container states the first container inspection
date and container expiration date.
If there is a question about the proper re-inspection of the
CNG fuel container, contact the manufacturer as identi-
fied on the container label.
