Can anyone give me some advice on taking out a gastank on a 1973 dodge Polara? Car stopped running suddenly- not getting gas.. I changed the fuel pump and filter and checked the lines-all clear up to the tank. I suspect the filter in tank is plugged-old varnishy gas. What is the correct process to remove or would you try something else first. If I put gas in carb it takes right off and runs. Any help would be appreciated.
