Un-used circuits in fuel tank????

[Roy]

what do you do with the following circuits? (2007 WRX)
Fuel Temp
Pressure control solenoid valve
Drain Valve
Fuel Tank Pressure sensor .
Do you need to fake the computer for these ? They are not used in the FFR Tank

If you have a Cobb AccessPort, or OpenSource, you just disable the codes for them.

If you are using the stock ECU attach the fuel temp sensor to the side of the tank. It helps with the fuel mapping.
