I use the Starion oil pump with a modified pickup tube to fit the Montero sump. I also use the Starion pump on all the 2.6 engines I build turbo or not, they are a better pump.

Most of these swaps use an external fuel pump and your DSM pump is for an in tank setup. They do not have a sealed case.
I use Bosch pumps for these swaps but Starion pump will do too.
I also flair the ends of the Montero fuel line and use the original hose sections from a Starion for the pressure line to the front
