I was a bit concerned that there would be a strainer in the tank that might block up, like happened on the Delica, and that dropping the tank would be required to access it.
But as you can see from the attached photos, a nice easy access panel and just a capture pot with pickup pipe sitting on four little plastic legs - no tank strainer at all.
I've unclipped the float for the level gauge to remove this part but it's clear where that attaches. I should keep an eye on the wiring too, in case the bio does something nasty to it.
