Good fuel flow from the primer to the injection pump bleeder?

Expert:  Curtis B. replied 1 year ago.

Check the fuel check valve, located on the return line on the injection pump cover. If it is plugged with debris, it can cause problems.

If fuel flow is good, and return line fitting not plugged, the injection pump is bad!
