I'm getting a strange phenomenon with my fuel gauge.
When the engine is running, the gauge reads about 10% lower than when the ignition is on but engine not running.
I noticed it when I filled up, checked the gauge as soon as I switched the ignition on then as I drove out of the petrol station I noticed the gauge reading significantly lower.
I tried the exercise again when I got home after refuelling (about 3 miles) and the same phenomenon again.
I can only think it might have something to do with the voltage (12v with ignition on and 14v with the engine running but I'm not a sparky so I have no real idea.
Any Thoughts?
