Thanks for all of the input.

A-zone pump was wired right and I saw it pump out the right end on a
bench test.

Here's a little more info and progress:
I have a 1987 car, & called FCP Groton asking about cross referenced
years for in-tank pumps and they said only a 1987 will work. Well, no
1987 cars to pull from in my area, so I grab a 1988 unit, snip off the
snap-on connectors for wiring in the trunk and hard wire it. Piece of
cake. Purple from the car goes to red wire to pump. Gray/white to gray/
white and brown to brown.

It's wired the same - red to pump on the positive post, gray/white and
brown to gauge, black comes back to ground. Thinking this morning I
would trash the sending unit and drive 70 miles to Dallas where a junk
yard says they have a 1987 unit, I put my 1988 unit in a bucket of
water and put 12v to it. It pumped water out just fine.

So, now it looks like the in-tank pump works, but I haven't checked
power from the actual wires that power the pump, so I don't know if it
works when I wire it up to the car.

That's where I am now.

Thanks!
