Need help with fule injection for 1.7 1970. cant get the fuel to the engine. tried putting fuel in every line. checked fuel flow to the pump. seems to have a little air past the filter (new) pump is sluggish after rebuilding and cleaning the varnish out. i would think yhay the pump would pull fuel to the bay right? with the engine turning over but not starting the pump runs. i do have some vacuum lines gone but the big main one is there and the distributer line as well. please help. im ordering a new pump because i just dont think it is operating as it should. thanks

The two most likely problems are that the hoses are hooked up to the wrong ports on the pump, or that the wires to the pump are plugged on to the wrong pins.
S == Suction; gets the hose from the fuel filter D == Druck (German for Pressure); goes to the driver's side fuel rail R == Return; goes to the Y that is hooked to the fuel pressure regulator and to the return port on the fuel tank --DD |
