Here is a diagram. My system is plumbed like a combo of diagram 1 and 2 in the Tanks, Inc instructions.
The ECU powers on the pump for 3-4 seconds with key on prior to cranking, and can be heard running for a few seconds after the engine dies. So electrically it is behaving as expected. I have adequate gas - 6-7 gallons. The tank also has a 3/8 vent line that is functional.
When the pump is running, I hear a fountain of fuel recirculating in the tank.
I have some spare fuel line. I suppose I could disconnect the pump supply to the reg, and let it blast into a gas can to see if the pump is cutting the mustard.
Due to work schedule, I get to troubleshoot this on the keyboard until Saturday afternoon.
