Low Pressure Pump
The low pressure pump and fuel level sending unit are installed in the fuel tank as a single assembly. The pump draws fuel from the bottom of the tank and supplies it to the high pressure pump. The 2 pumps are connected by a 5/16" fuel line that extends from the tank fitting to the inlet side of the high pressure pump.
The end of the pump pick-up is enclosed in a nylon filter which prevents the entry of the fuel tank contaminants into the EFI system. The fuel pump is not serviced separately. The pump and sending unit are available only as an assembly. See Fig 1 .
