a lot of people have the external ford fuel pump. I think its an E2000 from AZ or similar.
It fits an 86 Marquis with the 3.8L. They are from the fords that run an intank pump and an external pump. Which i think is pretty common for any late 80's ford with FI that has a larger engine or a turbo.
and tracker ones are intank, expensive, and you have to modify them to get them to fit inside a Samurai tank. YOu could probably buy a FI Samurai pump, but $$$$$$$$$
