November 1, 2012i have a 2003 3500 and am kind of baffled. about 15 seconds after i turn the key on the fuel filter cap blows off. i replaced the filter and cap and it still happens. i pulled the injection pump off the side of the filter case and with power is still pumping. i do have a FASS pump before that but it`s been on there for a few years and i`ve never had any problems before with it. any insight with this would be greatly appreciated. thanks
