Re: Multiple fuel pump failures
 

If you don't have the correct fuel filter, with bypass back to the tank
is plugged, you'll cut the eccentric cam lobe off as Doug as said. And you
have another filter inside the frame rail, on the drivers side above the
front half of the spring. There's a shield you have to remove to get to it.
