Someone please, help with advice

Long story short, I took worn out parts off my engine for replacing and painting.
Installed new waterpump, fan clutch, power steering pump, tune up, antifreeze.

Did me disconnecting fuel filter line from carb, and not plugging hose cause the fuel pump to go bad?
My passenger tank is overfilled, poured three spray can tops of gas in carb, still no start. I've double checked distributor cap and firing order is right.
What am I missing/doing wrong here?

If I dissconect fuel filter line at carb, and run it to a bottle how much gas is it supposed to be getting so I know its the pump? (meaning if it's a little, the pump is not working right.
What exactly should I do when I do this, will it trash my carb turning key without fuel filter/pump being connected to carb.

Truck sounds like it wants to start, but is out of gas. Forgot to add, truck has been sitting with no start for nine months. Is it possible that the tank switch in cab is on the driver tank? And I don't know what tank the switch is on, because the piece that goes around it and tells you is long missing and the buttom is not on lower dash but hanging on floor.
Battery is new.

1984 swb 305 edelbrock 4 barrel carb 1406
Dual exhaust
Dual tanks, driver side bypassed

Sincere appreciation and thanks for reading/giving advice to a noob, lol.
