When I replaced my entire fuel system, my original sender was worse than the one pictured. At the time I didn`t know that all the replacement pick ups wont read right, mine sucks !
I've stripped all the lines. Duster has a different vent system on it then my 68 Dart. The gas tank on the Duster has a three rubber hose in a series into the tank. I can probably bypass some of that as long as the vent tube is vented
