This is my deal , i just swapped in a 4.0L out of a 98 TJ into my 87 YJ I had to get a 95 yj fuel rail with a return line and adj fuel pressure reg and I aslo had to get a 95 yj tank in order to get my fuel system working right. now my question is what would I have to do in order to run a fuel cell so it runs right and works with this setup, just wondering what parts to I need to make this thing work, thanks for the help guys

Try a search for a post by CJ Lagos. He put a fuel cell in his 4.0 TJ.

No need to search! I used the fuel pump from the mopar mpi kit i think it was, i got it from hesco, they know what you need. Worked really well..hook that up and run lines to the cell.
