Put the new fuel filter in and my sputtering is gone. But the truck idles a bit high now, around 1100 rpms. What should the idle be set at? How should I do this? Where is the gas tank drain plug? I can't find the damn thing anywhere. This week I'll be kinda busy with school so I am only going to try and clean up the interior and make a new dash out of aluminum cause mine is broken( Previous owner had a visit from some radio thieves).
