Denso S4 TII fuel pump (950-0157)

This fuel pump (Denso 950-0157) comes up on Rock Auto's website when searching for an S4 TII fuel pump, but it also comes up when searching for a S4 n/a fuel pump. Searching the part number on other sites, the application lists show both turbo and n/a models, with a couple even listing 'All' under the aspiration tab where present.

Can anyone confirm that this pump is indeed appropriate for a TII? Anyone used it? How could it work in both models?

if you look up the Mazda numbers, all of the S5's used the turbo pump.

Denso's cataloging sucks donkey *****, but if you like you can look it up here too https://densoautoparts.com/find-my-part.aspx

I installed that pump in my 88 vert in November 2019, and one in my T2 in July of 2019. I've had no issues with either car since, probably have 1000 miles on the vert since the replacement.

Hope this helps.
