hi
why would a fuel gauge work fine when on petrol but not gas, both fuels work off the same factory fuel gauge, switch is on the left of the steering column and theres 2 relays next to the fuses and a small ecu. has gas in it and runs good but just doesnt show how much gas is in it but still shows how much petrol it has, would there still be another relay by the ecu for the fuel gauge changeover
if theres 2 relays near the fuses, would there be another one near the ecu on the left under the glovebox that could be tried first
