No. Sorry. After looking at the vin it is an 02. so that is not in front of tank
There is nothing in the frame - including no lift pump. (Has transfer pump between the two tanks)1/2" line from midship tank to motor. No security light. Just low fuel and battery light on dash. Does the fuel pump contol modual control the sending units too?
I understand how the system works. I have fixed many with the modal and lift pump set up forwrd of the main tank. All those have the steel midship tanks. On the one diagram you sent there is a relay "fuel balance pump relay" . Does that also tie into the sending units.? It does not appear to.
We figured it out. Put the scanner on it and read that the tank readings were 90% and 98% on front and rear tank which tells us it is a problem between the ECM and the dash.
