I popped a fuse on the frame pump once, the truck kept running fine with the motor mounted pump but with less pressure. A couple of weeks ago I tried filling up with Super Diesel. The pump was running really slow so I bailed and finished up with regular diesel. About 5 minutes later the truck started gagging on the highway, pressure was gone. The fuse looked fine, I used the bypass and the trucks is running fine, albeit at a lower psi. The pump (carter) must have quite with the vanes blocking fuel. The first time the vanes must have been "open" when the fuse blew. My first LP to go out died slowly. Is there any chance yours is dying slowing with the vanes in different positions when the failure occurs?
