Does anybody know if the fuel level goes through the ECU or if it's a separate circuit?

 

Does not go through ECU.

 

Understood. Thank you sir.

 

There's a little board in the cluster itself the tank wiring connects to. Most likely the problem is in the tank.

 

No, I just needed the information because I'm getting an AIM dash put in soon, and was trying to figure what I needed for fuel level. If it went through the ECU I was home free, and could just use the output there, but the sensor will need to be input through a math channel I belive, so that it will show on the dash.
