I am no mechanic but out of work so must try. I just got this old truck. It has (had) a cooking oil system in the back tank and diesel fuel in the front tank.

I was driving home with junk steel and it simply died. There is plenty of diesel as I just filled the front tank about 80 miles ago though the guage does not work.

It seemed to simply just stop. All the guages were in the normal range so no indication, even a hint of a problem.

I am assuming that it is a fuel problem. How can I test this? Is there printed repair information available? If the fuel system checks out are there tests that I can perform that would help me determine the problem?

Ok let me be upfront that I am not a diesel mechanic but with the info given and some patients I can help. Now first I need you to find the mechanical pump that is on the engine. Now one fuel line comes from the tank the other goes to the fuel filter to feed the injection pump and should put out 3 psi. So disconnect the line going to the filter and crank the engine over and see if fuel come out of the pump. If not replace that pump and it should run again. Here is a pic of the pump so you know what you are looking for.
