A few weeks ago my car developed a fuel leek. Found it to be at the seal for the first fuel filter. Since repairing it, the fuel gauge has a mind of its own. Never gives me a true reading. I know that it is the fuel sender unit that sits at the top of the fuel tank. Does anyone know if it is just a question of cleaning it or having to replace it. If someone knows about this issue and knows what to do or have done it, could they kindly post some pictures or give a detailed description. Found some pictures a few weeks ago of someone who had done it but as usual computer crashed.
