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

oh by the way, po bypassed the cold air valve and went with one fuel line to each rail. huh? no you don't need the cold start valve. Only kicks in near freezing anyway. But the fuel has to go from the 'd' to the passenger fuel rail then across the the front of the engine to the drivers side rail then the pressure regulator, then the return port of the pump. The return port of the pump is the one that is tee'd. Wasn't there a batch off AA three port pumps that had the ports reversed? IIRC though they had no SRD labelling on them. |
