Fitted some 17's on my 06 Fox today, jacked up both the front and the rear, before this I had half a tank of petrol, then once I had finish I had gone to have one bar left, was concerned so I went and put another £10 in and the gauge still wouldnt move. Now it stays on 1/4 all the time anm the needle doesn't work Anyboy know where my problem lies? Thanks.
