I just wanted to update in case it might help anyone in the future.

I accessed the top of the in tank pump, hooked a piece of hose onto the outlet, fired up the car and got a nice stream of fuel. I took the whole sending unit and pump out anyway. I found the clamp on the hose between the down tube and the pump just a little bit loose. Since I was in there, I added a second stainless clamp a little further down and that tightened it up. Grounds all looked good so back in it went.

The other thing I did was to remove the fuel pump relay and re flow all the solder joints. None of them looked especially cracked but I did notice the thing seemed to be getting awfully hot while driving.

Last tank I ran the car down pretty near empty and no signs of the idle problem at all. It's been almost 300 miles now and the symptoms have disappeared. I don't know what fixed it, maybe the FPR. Within the next couple weeks, the car goes to a 16 year old girl. I'll miss it but it will have a good home. Thanks for the help!
