I mounted a R31 unit and swirl pot in Ute tank only hassle i had (minor) was it sits up a little higher and touched the tray when refitting but had to cut out a section to get to fuel pump and remade another inspection plate/cover anyway. Had to extend the pump bracket to nearly touch bottom of tank/swirl pot/baffle.

We are going to do the same with wagon tank a bit similar to Coupe tanks size wise but im looking at using a Suzuki swift gti in tank set up there a lot more compact just have to get a beefier pump.
