Wow, In the tank, that sounds easy to get at. I have an issue where
the truck starts sputtering, (backfireing through the throttle body),
after running fine for a half hour or more. I figure I have a fuel
delivery problem, clogged filter or bad pump, or a computer chip going
south. I was going to replace the filter and the pump but wow, in the
tank, that would turn out to be quite a task.
