I wouldn't pressurize but I would smoke it. Isolate each section and smoke individually. As everyone said the forward fuel system is pressurized and will show leaks easily. Maybe smoke lines and tank and around the pump.
Around the pump can be hard to see leaks as usually very gunky down there so can be a pain to see
