I'm about to change the Power disks into Manual in my Duster... I like to FEEL my brake pedal... I had a 63 Dart Gt 440, /6, couldn't get her to stay runnin' after sitting 7 years at Grandpa and Grandma's... but I did!! You could Blow through the front to the back, sounded like a bong... pulled the tank , cleaned, ect.... I ended up driving from Tampa to Orlando and back with the gas can in the back seat in the long piece of fuel line coming through the firewall into the cabin we were sitting in. My brother that was with me had cystic fibrosis and I was just pretty kind of much crazy at the time so we didn't really give too much of a **** if we crashed an got on fire.. point I'm trying to make is the rubber line between the tank and the metal hard line I did not check because I was a young *** kid I also did not check mowing through the sending unit the other way towards the carburetor I don't know if this applies in your situation
