RB20DE: Fuel Filter Brown Gunk

My non-turbo R32’s been having a weird bogging issue, so I posted here and ya’ll suggested fuel filter as a possibility. Just unhooked the old one and a fair but of this brown gunky fluid came out— even as I type this, if I give it a shake, more comes out the bottom spout. It dries up into a mud texture and then gets crumbly, so I’d hardly call it a liquid.

Internet doesn’t have much info aside from some boating and diesel-related stuff… so, any ideas on the cause and a solution? Holding off on installing the new filter to avoid ruining it.

HR32 Bogging and Reverse Clunking

I own a manual, RWD RB20DE with pretty low miles and no rust, so pretty solid condition, but it’s having 2 issues that may or may not be related. Looking for advice (especially on #1)!

  1. Ever since I imported the car, if I start driving before it’s fully at temp, it will drive normally but then randomly have moments of underpower. The RPMs don’t drop and the car keeps moving, but it’s like the power is cut in half and it doesn’t wanna accelerate, and then randomly it’ll fix itself after a few seconds. This has historically only happened when I got impatient waiting for the temp gauge to reach halfway, but this past week has started happening at other random times too. Internet says maybe trans fluid, but idk.

  2. When I go in reverse, I can hear a sort of metallic clunking noise that corresponds to speed (the faster I go the louder it gets). My gut tells me maybe diff related or axle related, but again, not sure. Maybe it’s related to issue #1 via the differential?
