If I remember correctly these are much different from the Magnum engine fuel pumps. I searched and found the link I will post. As I remember it the assmebly has parts that can be replaced. I have never seen the whole assembly in a photo but recall Ralph P (RIP) posted about himself rebuilding his assembly with a new pump. Anyway search for his posts to get info about it and look this link over and see if it looks right to you. https://www.carid.com/1990-dodge-dak...er=1&sub-model[Liter][]=3.9L

 

Yeah, the pre-magnum engines were throttle body injected, which operates at a MUCH lower pressure than the magnums.
