Service bulletin SB171

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.

Fuel pumps used in aircraft fuel trucks for USAF in production at Hale and at Vehicle builders may have incorrect gasket material. This gasket is on the fuel pump used to move aviation fuel on this ground support equipment, not the vehicle engine fuel system.
