On my 87 272LE, I had to remove the tank for cleaning, too much crud inside. While out I saw the screen in the pickup and after consulting with others, removed it. My pickup and return tubes were not flexible, and the tank would've had to be removed to get to them.
I also cut about 20 " off the aft end of the bulkhead alongside the aft quarter berth to give me room to get it out. Between my steering quadrant (pedestal steering with cables) and the bulkhead, it was a real tight fit.
Take the tank out, clean out the inside, and get that screen out of there!
