Thanks to everyone for the information!
The tank was removed, flushed, and cleaned. (I did not have to imagine what it
looked like, I saw it, and what a mess!!!!) after cleaning, no inside coating
was applied due to concern with clogging the line pickup filter or screen at
the bottom of the tank. After replacement of the tank, there was fuel flowing
through the lines, but at a reduced rate. A filter was placed between the tank
and the pump, consequently it was easy to remove this filter and blow air
directly into the fuel line and into the tank without going through the pump.
All is working great now. If the filter is well secured to the tube, it is
then more probable that the filter was just cleared of 25 years of ?crud?.
Again, thanks for everyone?s information!

I cannot find my photos of the filter on the end of the fuel tank pick-up, but
as I recall, it was very well secured to the tube & it is unlikely that you
could have blown it off. Also, as I recall, if you have an original style fuel
pump, it has a check valve built into it which will prevent fuel from flowing
backwards thru the pump. You may have damaged this depending on the air
pressure you use when you blew backwards thru the pump. This might apply to
after market pumps, too.
If the tank has been sitting for 25 years, imagine what it might look like
inside! I would remove it & at the least, have it thoroughly flushed out.
If the tank has ever been coated inside with one of those proprietary coating
products is likely that the coating is separating & clogging the inlet screen.

Would it be correct, that on my BJ8 that has been sitting for 25 years, when I
blew the fuel line with air from the pump to the tank due to a clogged line or
filter, and it suddenly opened up, I probably blew a clogged filter off the end
of the pickup line inside the tank?
