You might try measuring the fuel delivery pressure at the Schrader valve. It can be done using a mechanical tyre pressure gauge (NOT a digital/electronic one = fire hazard). Get an assistant to turn the ignition key to position 2 while you carfully hold the pressure gauge to the valve. While the pump runs, you must see at least 50psi pressure. If not, I'd suggest you think about a new pump.
You said it's got the earlier type fuel filter. Did you see it yourself?
