There is no room the header is almost right against the filter housing where the sending unit would thread into, it points towards the passenger side, not back. Seems like the old one was completely different, with just a small threaded piece with a copper piece coming out, the new one is about an inch and a half long, where the old piece was only like 1/2" long and just cleared the header. I cab;t get in there to get a good picture.
