Service bulletin ENP-651

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Type 3 and Type 4 CNG fuel cylinders used in natural gas fuel systems expand and contract in normal operation. Mounting systems must compensate for these changes. The isolators are a maintenance item and periodic replacement is needed. An improved J-bracket was developed and should improve isolator wear.
