Well - I took the tank to a recommended welder, having washed it out with soapy water and let it vent for a while. They have blown it up. (the guy is ok, didn't check for fumes, didn't open the lid, didn't call me to ask for the key to open the top, just took a torch to it).
Is it a CB550K or a CB550F, I'm presuming it's the F model but at a pinch you can fit the 500 style tank to it but you also need to change the seat to the 500 one as well. Just an idea in case your struggling to find an F type tank.Just found this, looks ok and reasonably priced.http://www.ebay.co.uk/itm/GAS-TANK-HONDA-CB550F-CB550-CB-550-F-SUPER-SPORT-FUEL-CELL-/382213539953?hash=item58fdb3c871:g:mPEAAOSwCkZZVrhb
