Well, not a lot of chatter here, I expect it has been seen by all many times, lol, but I finally am about to bring this to a close, successfully I hope. After a couple of rethinks, I will pressurize the system tomorrow with new gasoline and start it.
Last week I looked over Mac's how-to one more time, and while reading it something made me check the hose I had bought to replace the outer hoses which would hold the filter. It was the R9 version...but I noticed it had "50 psi" on it, and I took that to be the max for which it was rated. I have seen various numbers to describe the psi in the fuel system, but most of them were higher than 50, so since I just wasn't sure where the lowest psi in the whole system might be, I went ahead and got two more lengths of the R10 mentioned and seen above. Pricey but at least I know all the hose replaced has an identical rating, 100 psi. This filter is not small, same size as oem, but try to find one of those smaller ones that will do 10 microns.
I also went ahead and decided to order replacement fuel filters that filtered at the same rating as the oem, 10 microns. These filters appear to be direct replacements for the KL145, with ratings of 80 psi.

I got FI clamps from two different sources, and something a bit odd about one of the brands...they seem to have a softer metal neck under the screw, because they would actually screw down until the two pieces pressed together by the time the threads could no longer clamp. The other set of clamps seemed to reach max clamping force before the ends began to bend. Not a huge deal, but different.
Before I put the new gasoline in, I noticed what looked like some flakes of debris in the tank after the gas all evaporated out. I suppose it did that after being dry for several days. There wasn't much, and I suspect the dual sock will prevent most of it from going into the pump, but I went ahead and dumped in a few cans of SeaFoam and sloshed it around well. Then I vacuumed all the liquid out again, not sure if I got it completely out, but lots of straw-slurping, so about all I can do to clean the inside.
Tomorrow I will put enough gasoline in to cover over the flange and see if any seepage is going on, and then turn on the ignition and see if everything holds with no leaks. Then I will start it.
Thanks for the advice on this thread, hope it hasn't been too boring, lol.
Oh, the place where I got the filters, they also carry a corrugated rubber hose that will replace the hose inside tank instead of buying the straight lengths. 15 bucks for the length and some clamps. Makes for a tighter package, but I'd already fitted mine so didn't use it this round.
...have just been putting vaseline in there. I will stop spamming now
