Corrosion May Cause Fuel Line Leak

A corroded fuel line can leak fuel, increasing the risk of a fire.


NHTSA Campaign Number: 22V851

Manufacturer Coach and Equipment Mfg. Corp.


Potential Number of Units Affected 353



Coach and Equipment Mfg, Corp. (Coach and Equipment) is recalling certain 2016-2023 Phoenix transit buses equipped with Roush fuel return lines included in GEN 4 and GEN 5 LPG Conversion Systems that were installed on vehicles sold or registered in Connecticut, Delaware, Illinois, Indiana, Iowa, Kentucky, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, Virginia, Washington D.C., West Virginia, and Wisconsin.
