why?...going to start at the fuel souce and work forward and see what is clogged and what is clear. Even if just changing the filter solves the problem, I will still what to pull the strainer and see what's going on in the tank.

Plus, as you point out, I have done nothing with the car yet. I plan to replace both filters and check/clean the strainer anyway. If for no other reason than to have new filters for a fresh start because the current filter age is unknown. Then I will have a good base line.

I just bought the car a couple months ago. New trans filter, air filter, oil change, adjusted valves, turbo swap (car had wrong turbo, CA style).

I had just been waiting to run some WVO and letting all the crud get flushed out into the filters before changing them.

I'm guessing that's exactly what happened.
