A fuel pressure pulse damper includes metallic damper body defining a chamber in which a flexible diaphragm is received in a manner to dampen fuel pressure pulses between a fuel pump and fuel injectors of a vehicle fuel system. The damper body includes a barbed fitting to receive fuel form the fuel pump and quick connect fitting for connection to a fuel rail for supplying pressurized fuel to fuel injectors of the vehicle engine.

Vehicle fuel pulse damper

A one-piece check valve is provided for a fuel filler pipe connected to a vehicle fuel tank to provide a fuel filling passage communicated to the fuel tank. The check valve comprises a thin sheet of material shaped to comprise a mounting portion, a flapper valve and an intermediate connecting portion that connects the flapper valve and the mounting portion with the connecting portion being contoured so as to normally impart a spring bias to the flapper valve to close off the fuel filling passage. An elastomeric seal is fastened on the flapper valve or on the fill pipe in a manner to provide a liquid fuel and vapor tight seal when the flapper valve is in a closed position relative to the fuel filling passage. The flapper valve is opened when fuel is introduced into the fuel filler pipe to permit fueling of said tank.
