Just read article on a 416b caterpillar regarding fuel issues. Starts fine, will run short distances then quits, have replaced fuel pum, fuel lines, fuel separator. Called in a professional diesel mechanic and “he doesn’t know”?

416 B extendahoe backhoe, 1996, 8SG04463

Two things to check, the fuel outlet line from the tank, which may be sucking up debris, or the fuel shutoff solenoid that can be overheating,, and killing th engine. How long after it quits will it restart?

It runs out of fuel, there’s no fuel in the fuel filter when it does this. Setting still it idles indefinitely, give it fuel to move out of shop and fuel filter is emptied

Then the fuel outlet line to the filter needs to be removed, and the line blew out back toward the tank, with the tank cap removed. And also check the fitting at the filter for any debris too large to enter the filter.

Machine quits minutes after operational. Fuel filter is empty. All checks we have made indicate there is air coming from somewhere. Ran all tests we know to do. Considering replacing injection pump and that's another story. Two diesel mechanics, Ajax Diesel and Caterpillar, were unable to fix. Ran same tests we did and nothing else. Like I said, we are at the injection pump and there's no guarantee thats the issue. There's air in the line.
