I have a 1992 XJS 12 cylender with 35,000 miles. Havent used the car in a year. Today a winning started comming from the fuel tank (I think). I opened cap and seamed to be too much pressure and fuel flying out.Warm fuel. Is the pump winning because it is on way out or could the fuel filter be clogged? Car runs good but sometimes seams like its missing. Was going to change spark plugs tomorrow but I thats a different problem. I am wanting to solve the fuel winning noise issue.
