Often the fuel pumps will dry out after sitting an extended period of time. The bit of crud in there can cause the one way valves to not work. Sometimes merely priming the pump with a bit of fuel poured down the line will cause it to develop suction again, other times you have top open it up and clean it out.
A major problem with the old M38A1s is that the rather course fuel fiilter built into the tank does not screen out the really fine particulate. These can build up in the fuel pump causing it to not pump, or else get into the needle valve and cause the jeep to flood, especially when it is hot and sitting at a stop sign. An inline fuel filter installed in the short flexline right before the pump will cure that problem.
