Mr Hagg and others here are stating the life expectancy on these pumps is roughly 300,000 to 400,000 miles. If you have not checked what you have by removing the pump head, I would do that ASAP. And if it were me, I would pull the pumps and rebuild, cheap insurance. But sadly, no real guarantee.

Do you know what the avg cost is for either method? The fuel pump since we've had the truck has never been inspected nor changed. We bought the truck roughly around 412,000 miles. It may have been done before, but not by us.
