Barko,
it's likely to be the fuel connectors. You should ring your nearest Triumph dealer with the engine no. and ask if it's been done (we can do that in the UK anyway ...)
If it has been done it could still be a problem The recall was for the male connector only [fuel line side]. The receiving side female connectors are not included in the recall so can still crack. Also it's very easy to split the O rings on the connectors - my dealer did this on my Daytona. If you need to buy some these folk can help-

There's no shutoff - the connectors are supposed to do that.
No Clymer. There is a Haynes that covers 97-00 and you can get CDs of the factory manuals on Ebay.
