Need help with Fuel System 67 C20 327

[71GMCNC]

Hello all,

Ok just to make sure I am not missing anything here as the system seems quite simple. I am trying to get my C20 running. It runs when I use starting fluid but then stops.

I have undone the fuel line into the carb and then turn her over and get no fuel coming out.

I traced past the fuel pump to a rubber hose that connects the pump to the line going to the in-cab tank. That hose was collapsed and was at a weird angle to I replaced and put an inline filter while there. Still no gas present inline.

I undo the fuel line going to the fuel sender and blew out the line. All is cear however no gas in the line.

That brings me to the tank... I replaced the tank due to excessive rust and failed sender and put a new tank and sender in.

So with everything connected other than the line going into the carb and I crank and crank to get the fuel into lines and to the carb yet no matter how much i crank no fuel comes out. I have killed a battery doing this.

So this would leave the fuel pump being bad correct? Sorry, I am electronic savvy and not mechanical. I am new to being a backyard mechanic.

Any input is greatly appreciated.

On a brighter note I ordered kick panel speakers and estuchean (spelling?) for the window crank and door handles interior for the GMC.
