Or strip it down (you will need to anyway to stop swarf getting into the fuel chamber if you were to drill it), heat the body up with a high temp hot air gun (or carefully with a flame) and you should be able to pull it out and push a new piece of tube in, it's only a press fit so when the ally is heated it should come out easily enough.
I big self tapper or thick wood screw should get enough purchase on it to then be able to just pull it out.
Failing that drill it out - you will probably find it will start spinning round and start working itself out anyway.
Which one is it? and where are you? I have an SU that was from a late P6 V8 if you need it, cant remeber whcih side it is. (it was lost and while lost I sold the other one), If you can pick it up or pay the postage it's yours
