Unhappy Low fuel Pressure

A buddy of mine has a 67 Bird 400. Been having trouble with fuel pressure. When he starts it up pressure at 6-7 psi. After about 5 mins it drops to 3 psi and the motor starts to back fire and runs ruff. He's running a electric pump which seems to be installed correctly. HE was concerned that the pump was not getting flow from the tank so he ran a line from a gas can direct to the pump, same problem. Any ideas would be appricated.
