Hey, I have a 1997 f150 4.2 with close to 200,000 miles. It runs like a champ with no codes being thrown, but I feel like especially after sitting the truck tank loses pressure to send gas at the startup. The truck has never failed, just takes longer when having a cold start. If I start it up after driving for a bit has no problem. Sound like a sensor or seal gone bad on tank? I do hear a slight hiss in the engine bay when I cut it off, possible fuel line or something like that? Thanks
