PUT NEW FUEL PUMP IN & SENDING UNIT IN, AND STILL DOSE NOT WORK
Your issue could be the cluster itself. Do you have power and a good ground for the sending unit?

I would also check routeing of the fuel lines, if they are too close to hot parts it can vapor lock (Boil Fuel). You could also shoot come carb cleaner down the carb to see if it will help. and check the wires to the pump and sending unit on the tank the could be loose and causeing the truck to shut off.

could be just a ground problem or a sending unit problem but not a pump problem.
check and make sure that the gas tank is grounded. check also the signal wire from the sending unit that it is not loose or cut. if all the wires are ok, then it is the sending unit which is faulty.
tnx 4 using fixya,

Test the gauge by using a test light ,and grounding the test light clip to a good known ground,then touch the pink wire on the connector harness going to the tank,with the connector unplugged,and key on,the gauge will move slowly to the empty mark,and lower ,then remove the test light and it will go past full,if it does this,it is a good gauge,and the sending unit,was put in wrong,or the part was bad.
