E30 '87 to '89 fuel tank conversion
I have a 1987 325is that had a rusty tank so I picked up a clean tank from a 1989 325i.
I am running into a major problem figuring out where the lines need to be re routed. The early model pump has two metal inputs on the top of it, one to a hose that leads to the filter I believe and one to a slightly bigger hardline that runs the underside of the rear seat, turns, and heads all the way up to the charcoal canister along side the other two hardlines . The late pump only has one input and it goes to one hose on the top of the newer tank. I already cut a hole in my floor and mashed the mounting point for the old in line pump so telling me I need to get a same year tank is not going to help my situation. I know this conversion has been done, just am super confused.
The problem I am having is that the hardline from the early setup is not only right in the way of the new tank (tops out when I go to put it in), but it also means I have one extra hose with nowhere to go.
I searched the forums and cannot find any answers. Can anyone redirect me to a post where this has been done, or tell me where that one line is supposed to be going, or provide some photos or diagrams? I am not sure if the late models have a 3rd hardline or not. Pretty damn frustrated with this as my car has been out of commission for a month and every time I try and get some help people just make me feel stupid but can't provide a solution.
Any help is much appreciated, thanks!
