I have just had a new fuel tank fitted and now the fuel gauge doesn´t work. Garage has removed and then put back the fuel tank and say they do not know what is causing the problem. Any suggestions
could be wiring on tank unit, may be an earth problem,might be float caught on baffle in tank or float either punctured or dislodged from lever.i take it tank unit was working when they removed it? [just a few possible causes]
