Took a 2017 5.3L and E92 ECM and put it in my 37 Ford Wild Rod. Trying to figure out the fuel sending unit requirements to run through the ECM. I had a fuel cell built for the car and it currently has a 0-90 Ohms GM type sending unit installed. I'm not getting any reading for fuel level through OBD AutoMeter DashLink II which bluethooths directly to my iPad.
I've called performance shops that sell senders but they have no idea what I'm working with. Any ideas what I need to be looking for in a sender. Thanks, Rick

 

40 ohms full to 250 ohms empty. But if you set any DTC's it may default to empty until the codes are cleared.
