Well, I finally got around to dropping the tank to changeout the dying fuel pump.
There were lots of Oklahoma red dust/dirt everywhere (car came from Oklahoma). I expected to see lots of same debris in tank, suspecting that is what was causing the reduced fuel pressure.
The hoses looked great.

Much to my surprise, the inside was extremely clean on the inside.

After sloshing it around to collect any debris, this is what was found inside ..... notice the flat slivers.... thought they were some kind of leaf.

They looked like some sort of flattened solder. Very malleable and soft..... ????

Fuel pressure is now a solid 3 psi and occasionally hits 4.
WOT with high revs of the 215 V8 sucks it down to 2 psi. Since it doesn't sustain those high rpms for long, a stock (Carter replacement) fuel pump should suffice.
