# Service bulletin ENP\-516

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

This manual replaces three individual manuals: ?Truck and Tractor CNG System Operation Manual, ENP\-007; ?CNG Fuel System Inspection Guidelines,? ENP\-468 and ?CNG Maintenance Interval Guidelines,? ENP\-493. The simplified ?CNG System Users? Manual,? ENP\-314, is available for download from the Agility Fuel Solutions LLC \(Agility®\) website.

Systems or specific components may vary slightly from this text, but the operating principles and functions of the components are the same.
