Fuel gauge appears 1/2 when full

[janek75]

Hi all,  hope you could shine some light on the issue my MY15 Tracer developed recently. After re-fuelling to the full, the fuel gauge shows only 1/2 full tank. It takes 10-15 minutes to display the correct level. I'm not sure what sort of level metering system is used in Tracer (floater/level probes?) and how to troubleshoot. Maybe it's just a loose plug?

Any ideas are welcome.

Shares the same plug as the fuel pump. 99% certain that the pump and sending unit for the gauge are the same part and you would have to replace the Fuel pump assembly. 

I’d follow the procedure in the manual for testing, which for accuracy will involve draining the tank and removing the pump, which means you should be prepared to replace the gasket as well.

the other causes would be 1- too much resistance in the wiring or at the plug. Clean the connections and check connector for the plug closely. or 2- the sending unit is sticking, due to it being restricted somehow or damaged or contaminated with some sticky fuel residue. Finally 3 - problem with the Instrument cluster or ECM or wiring in between. 

going off memory here, so check the service manual.
