Disconnect the fuel line on the other side of the fuel pump.
Unscrew the commodities property the pump mounting bracket in place.
Remove the sometime fuel pump
Remove whatsoever gasket material from the pump mounting surface using a plastic scraper to prevent damaging the surface.
Apply a thin layer of gasket sealer to the new fuel pump gasket and place the new gasket in position.
Position the new fuel pump in place and secure information technology with the pump bracket.
