If you idled the truck, then got on it (float bowl would be full if pump is working enough to do that) did it make a difference?
Just trying to figure out the commonality with your experience and his...still a lot of variables, but at idle the pump should easily fill the float bowl, and that should give you enough gas to get up to 30+MPH. (of course, assuming the pump was moving enough to fill it at idle)
Also, did you have weak performance even getting to 30MPH, or was it more like a wall that you suddenly hit that you couldn't overcome?
