txsport06,
This is probably not what you want to read, but I just had the same problem with my S4. I called Freedom Cycle in Reno, NV and was told that it takes a special Easy-Out like tool to remove the fittings from the tank. The tool was about $60 from Mac Tools.
I opted to send the fuel sending unit to Freedom Cycle. They repaired the fittings, sent me new aluminum male ends for the quick-connects, and replaced the fuel filter at no charge as this was a recall issue.
Freedom Cycle did this without knowing me and totally from a phone call. I paid shipping both ways and bought a K&N filter just to throw a little money into FC's coffers. If you are anywhere close, give them a call.
