Well recently acquired this car. Haven't done much besides new battery,alt, belts, and fixed some small oil leaks. I found this in the trunk (small box that looks similar to gas versions fuel pump next to fuel tank) it has a plug on top that's held on by three Philips screws when I opened it looks like two probws. . On my 85 it had a similar box for fuel pump. So just curious as I think this car was swapped to this eco diesel.
