Absolutely nothing. Must be in the filter by now!

My problem is I can't get the tube-nut off the union on the tank. Darn thing is corroded on there and the brass union refuses to be held by anything I can lay my hands on... I may just have to saw it off and pray I can get another (14mm... with a 15mm tube-nut. WHERETHEHECK am I supposed to get those?).

Guess that's three places I've found so far that are metric (other two are steering box and caliper bolts for those keeping track).

And it was running soooo nice too.

a common FORD mesh filter fits and is way cheaper then the volvo part

I don't know if there is room for this on an 1800, but take a look if the other ways don't work. I ruined that pickup strainer on my 142E when I tried to remove it to clean it, so I left it off and spliced a replaceable filter between the tank and the fuel pump. Works fine and has the advantage that you can see when it fills up with junk and swap in a clean one. Actually, I've only had to do that once. That was right after I installed it last summer, and quite a bit of debris was still coming out of the tank. I had knocked a couple of fairly large dents out of the tank, dislodging a substantial amount rusty whatever.

As Ron says, if you have not damaged it you can clean it up and re-install it. I would think you could also simply pick up some vinyl or brass mesh and put it over the tube with a zip tie. When I re-worked my tank I unsoldered the pickup tube and removed it completely before cleaning and sealing the tank. I used the kit that POR makes and was pleased with the results. Just be sure to follow all the steps for whatever system you use. The last thing you want is a sheet of plastic sealant peeling off the inside of the tank and getting sucked into the pickup tube! If you do any soldering, just remember that gas fumes are nasty things to have around fire and sparks.

That's the prefilter. If you didn't hole it when extracting it, you should just clean it by blasting it with carb cleaner and reinstall it...but only after cleaning out the tank of all the rust in there and sealing it...use one of the commercial epoxy kits...but only after a good internal cleanup with about a gallon of traprock poured into the sender hole, then strapped (for instance) to a cemet mixer for rotation for an hour should prep it well for an epoxy inside coating job. Mask off the pickup tube to prevent clogging it. Good Luck
