1968 BRONCO GOES TO THE CRUSHER?? OR...WILL IT RUN??

What happens here

With the external fuel source connected, the presenter turns the ignition key to activate the electric fuel pump. He listens closely for the pump to pick up fuel, but it does not. He then attempts a 'military fix' by tapping the pump with a screwdriver, hoping to dislodge any stuck components. After a few more ignition cycles, the pump still fails to draw fuel. Finally, he uses an air compressor and an air blow gun to force air through the fuel line into the pump, attempting to clear any blockage or prime it. This action successfully dislodges something, causing a burst of fuel to spray out, confirming the pump is now capable of moving fuel.

Goal: Get the electric fuel pump to draw fuel from the external source.

inside give it the military fix here you guys were ever in the military you know about that pigs mechanics chime in now okay this is the time where you chime in maybe I need to prime this pump I I don't know pour a little more in the carb I'm going to turn it on and off a few times and see if that helps it pick up fuel alright let's try it again whoa yeah daddy likey look right there you see her she's seen that things start to go she's like ho-ho he just started cheesing because I've spent a bunch of money on it and she doesn't think it ran so she's over there smile look at that smile I can't think of a reason in the world why this fuel pump wouldn't pick up fuel we're gonna do something really stupid it's as if the little motor and the pump is spinning but nothing's happening maybe if I ticket loose and try to siphon a little bit of fuel through here and got a good mouthful of gasoline Oh angle iron for bumper head got me on the knee I just oh that bumper got me again okay here comes gasoline in your mouth do ya I'm being laughed at by a lot of people that have a lot of mechanical knowledge right now and I do realize that but my troubleshooting methods are American and that's all I can do is just be a good American and troubleshoot by drinking gasoline and being and ding-dong you wouldn't think something brand-new would be screwed up right out of the box maybe ruining the pump by letting it run dry I'd probably what one of you guys is thinking right now hey you're just ruining the pump now me before we give up on the fuel pump I'm winning out my little Dewalt pancake compressor and will try and just blow some air through this pump and see oh-ho-ho-ho-ho-ho soon as I squeeze the trigger it took it it blew something out of it is it squirting out of the bottom yeah
