Chris, not trying to be condesending...but lap means - to grind (finely) the surfaces between the the feul tap and the body of the fuel tap it sits in.
It makes both surfaces sit evenly against each other thus preventing a fuel leak. As Mike has suggested, valve grind paste should work well.
Doing this should provide a pretty good seal. It may still weep a fraction initially but should "Take up" after a while and stop leaking.
