Once the manifold cooled down, it started and ran fine again. I had a bad fuel pump in another truck and it would drive fine at 35 MPH but sputter and stall if I maintained 60 MPH. Electric fuel pump solved that bad mechanical pump problem. This has no problem running at 65 for extended periods of time, but if I’m at the traffic light or stop and go traffic, that’s when it seems to get too hot. Just needs more air flow under the hood and across the manifold.
