Sounds like to same effort I had to put into my first tank.  Assuming the 
groove in the tank, the gasket and ring clamp are completely clean (no rust, no 
old gasket material etc.) I would just used a little soap or silicone.  DON'T 
use grease or oil as the gasket will swell.  I've used both old and new gaskets 
(though I haven't bought a new one in ten years).  To clean the gasket prior 
to assembly use a pumice hand cleaner to get down to clean, deep black rubber. 
 Then soap it a little and SLOWLY tap the ring clamp until it seats against 
the stops.

For what it's worth, my daughter's (ex)boyfriend had a leaking seal in his 
F**d Escort that was caused by the last repairman adding silicone.  After it was 
cleaned up as above, it all went back together again with no leaks.
