What NHTSA recorded

On certain chassis built with lng engines, the lng tank's primary and secondary relief valves could fail to open and relieve tank pressure.

Possible consequence

This could cause ice buildup on the discharge side of the primary and secondary pressure system allowing the relief system to freeze and become blocked resulting in over pressurization of the lng tanks creating the risk of catastrophic tank rupture which could cause serious injury or death.

Remedy

Dealers will retrofit the lng tanks with a new primary relief valve pipe away tube and a new ventilated shroud. The recall began on may 14, 2004. Owners should contact fontaine at 1-800-544-8175.
