Keith Browning Posted November 6, 2010 Share Posted November 6, 2010 I discovered this on a 2008 F450. This is the take out for the high pressure fuel pump at the glow plug control module. I noticed the heat shielding was worn away and decided to look at it closer. The inset shows the two VPWR circuits for the VCV and PCV worn through exposing the wire. I imagine that cover is conductive and could potentially ground those circuits. I imagine this could also have eventually worn through the wiring but it is after all a metal coated cloth shield making that fairly unlikely. This truck had bad thermostats and an unresponsive EGR valve (which is on that circuit) but the valve was bad. I doubt the chafe had any influence on that. Just something to stick into the back of your mind's. :hammer: Quote Link to comment Share on other sites More sharing options...
