I finally took it to the local HD shop. they ended up repairing the oil pump and replacing the piston ring set for some reason. The total cost was $826.73. I have been riding Harleys a long time but still feel like I've been screwed when taking it to the dealership....

I understand that removing the tank was not what you ended up needing to do, but, in the interest of helping anybody who might come across this thread while searching for a way to get their oil tank out I offer this bit of advice.
My experience is with a 1999 FXST EVO, so this won’t apply to everybody. My steps were these:
1. Drain the oil. Leave the plug off and let it continue to drain why you’re disconnecting other stuff.
2. Remove the seat and then the battery. You can remove the battery tray if you want to, but it’s not required.
3. Remove the bolts that hold the oil tank bracket to the frame. I’m not talking about the bolts up behind the tank itself, I’m talking about the bolts that are right there in the battery box. Take ‘em out.
4. Remove the two bolts on the bottom front of the tank. They are through bushings, take the bolts and bushings out.
5. Loosen the bolt that holds the right side lower bracket onto the frame. You don’t need to remove the bolt (in fact, you might not be able to because the nut will spin the bolt causing you to cuss uncontrollably). Once loose you can swing that little bracket toward the front/right and get it out of your way.
6. Let the oil tank drop a little and then remove the nuts that hold the tank to the bracket. Unbolting the bracket is a ton easier than unbolting the tank from the bracket. Once you are able to get the tank to drop those little nuts on the back are easier to get to. The bracket will come off and out of the way then.
7. Disconnect the oil lines.
8. Move the oil tank slightly forward and down, jiggle it a little and remove it from the right side.
9. Have a beer.

Did you ask exactly "what" they repaired on the oil pump and "why" they did rings? " ...for some reason..." is not an answer.

On this forum we bust each other's ***** a lot, because we have known each other for years, so lighten up...
And if you would have looked at my sig line you would have seen that I didn`t need to be told that Harley Davidsons last more than 10 years, I bought the one in that pic new in Dec 1988.
Cheers.
