RomRaider

Is there a way to calibrate fuel level sensor? Specifically Subaru Impreza 2006 2.5i NA MT (E2VH202C - 4312087206)
Is it even correct to expect that there is a possibility to calibrate fuel level sensor in the car using RomRaider or some factory procedure?

Why am I asking? I am building a VW T2 Bay bus with Subaru engine. I also use Subarus fuel pump, as the fuel system is non-return type and I was not sure if an aftermarket not in-tank pump would work. The Subaru has 2 fuel level sensors in series, for me, only one fits the tank, I would avoid hacking the other into it. As the 2 sensors are in series, a fixed resistor trick would not work.

All the best!
