Ever since i have owned my turbo it's never given a true reading on the fuel gauge, unless its totally full that is lol I know when its nearing empty when it goes back up to 1/4 again... lol, ots wierd to explain, but thats how i've go used to it all these years!!

So... how easy is it to sort this once and for all? Is it a simple case of just swapping a sender unit, or would a new tank be needed?

Any info would be appreciated, including costs or links...anything
