No expert on these truck have had mine for some 2 whole days now. 1953
3100 AD I would suspect it is in the carborator. When it need lots of
fuel at higher rpm it is ok and that would help to dismiss the fuel pump
and filter, which would limit the volume and when lot of fuel is needed
and make it stumble. The carb is running lean I suspect. You can
disconnect the fuel line and check volume and pressure, and the filter
never hurts to change out though. Let us know what you come up with
though either way. Ed ke6bnl So.Calif.
